Misc code cleanup.
Working AJAX form replacement function for landing page.
Minor code cleanup, commenting added.
Incomplete version using AJAX.
Non-AJAX, DHTML-only approach;
AJAX wasn't necessary, since possible content for form is limited to two known options;
DHTML may avoid issues with variables populated by PHP, and other quirks of loading elements piecemeal;
BUG: userCard.php not displaying on live site, but working on localhost.

Loading userCard.php directly (/userCard.php?prof=0&me=0) showed numerous mysqli errors;
Listed mismatched bind_result args, and improper free_result methods;

This version alters the syntax, and disables error reporting;
If this version works, it should still be revisited to check whether adjusted syntax is correct;
And to consolidate or fix the SQL queries in general;
Sync with upstream.

Merge branch 'master' of https://github.com/elizuck/circulate into modalNotifUserCard
Tweaks to JS. Intermediate working stage.
Working version;
Prevents loading notif again if it's already selected and loaded;
Adds prototype method to JS array constructor 'notAgain(),' which
compares a current and last value, and returns false if they're identical;
Corrected sequencing for loading animation and AJAX;
Differentiate between real and simulated click events, so scrolling functions will always fire on notification modal launch.
Possible fix for CSS inconsistencies for notifArticle.php, when notif modal is called from non-feed pages (e.g. Circulation, Subscriptions, Sections).

Enable inline extension installation
