*/

If you wish, you can define QA_MYSQL_USERS_PREFIX separately from QA_MYSQL_TABLE_PREFIX.
If so, it is used instead of QA_MYSQL_TABLE_PREFIX as the prefix for tables containing
information about user accounts (not including users' activity and points). This allows
multiple Q2A sites to have shared logins and users, but separate posts and activity.
define('QA_MYSQL_USERS_PREFIX', 'qa_users_');
*/
/*
If you wish, you can define QA_COOKIE_DOMAIN so that any cookies created by Q2A are assigned
to a specific domain name, instead of the full domain name of the request by default. This is
useful if you're running multiple Q2A sites on subdomains with a shared user base.
define('QA_COOKIE_DOMAIN', '.example.com'); // be sure to keep the leading period
*/
/*
If you wish, you can define an array $QA_CONST_PATH_MAP to modify the URLs used in your Q2A site.
The key of each array element should be the standard part of the path, e.g. 'questions',
and the value should be the replacement for that standard part, e.g. 'topics'. If you edit this
file in UTF-8 encoding you can also use non-ASCII characters in these URLs.

Set QA_EXTERNAL_USERS to true to use your user identification code in qa-external/qa-external-users.php
This allows you to integrate with your existing user database and management system. For more details,
consult the online documentation on installing Question2Answer with single sign-on.
The constants QA_EXTERNAL_LANG and QA_EXTERNAL_EMAILER are deprecated from Q2A 1.5 since the same
effect can now be achieved in plugins by using function overrides.

Out-of-the-box WordPress 3.x integration - to integrate with your WordPress site and user
database, define QA_WORDPRESS_INTEGRATE_PATH as the full path to the WordPress directory

will be taken from WordPress automatically. See online documentation for more details.
define('QA_WORDPRESS_INTEGRATE_PATH', '/PATH/TO/WORDPRESS');
*/
/*
Some settings to help optimize your Question2Answer site's performance.
If QA_HTML_COMPRESSION is true, HTML web pages will be output using Gzip compression, if
the user's browser indicates this is supported. This will increase the performance of your
site, but may make debugging harder if PHP does not complete execution.
QA_MAX_LIMIT_START is the maximum start parameter that can be requested, for paging through
long lists of questions, etc... As the start parameter gets higher, queries tend to get
slower, since MySQL must examine more information. Very high start numbers are usually only
requested by search engine robots anyway.
If a word is used QA_IGNORED_WORDS_FREQ times or more in a particular way, it is ignored
when searching or finding related questions. This saves time by ignoring words which are so
common that they are probably not worth matching on.
Set QA_ALLOW_UNINDEXED_QUERIES to true if you don't mind running some database queries which
are not indexed efficiently. For example, this will enable browsing unanswered questions per
category. If your database becomes large, these queries could become costly.
Set QA_OPTIMIZE_LOCAL_DB to true if your web server and MySQL are running on the same box.
When viewing a page on your site, this will use many simple MySQL queries instead of fewer
complex ones, which makes sense since there is no latency for localhost access.
Set QA_OPTIMIZE_DISTANT_DB to true if your web server and MySQL are far enough apart to
create significant latency. This will minimize the number of database queries as much as
is possible, even at the cost of significant additional processing at each end.
Set QA_PERSISTENT_CONN_DB to true to use persistent database connections. Only use this if
you are absolutely sure it is a good idea under your setup - generally it is not.
For more information: http://www.php.net/manual/en/features.persistent-connections.php
Set QA_DEBUG_PERFORMANCE to true to show detailed performance profiling information at the
bottom of every Question2Answer page.
*/

Returns the $qa_content structure for a question list page showing $questions retrieved from the database.
If $pagesize is not null, it sets the max number of questions to display.
If $count is not null, pagination is determined by $start and $count.
The page title is $sometitle unless there are no questions shown, in which case it's $nonetitle.
$navcategories should contain the categories retrived from the database using qa_db_category_nav_selectspec(...) for
$categoryid, which is the current category shown (set $categoryisfavorite to whether the user has favorited it).
If $categorypathprefix is set, category navigation will be shown, with per-category question counts if
$categoryqcount is true. The nav links will have the prefix $categorypathprefix and possible extra $categoryparams.
If $feedpathprefix is set, the page has an RSS feed whose URL uses that prefix.
If there are no links to other pages, $suggest is used to suggest what the user should do.
The $pagelinkparams are passed through to qa_html_page_links(...) which creates links for page 2, 3, etc..
