* Renaming some variables to make them easier to understand. And following naming guidelines, basically. (mass_attach/attachui.js)

! WedgeDesk, still the untested beast, has the one remaining add_css_file call I had to simplify. (wedgedesk/src/WedgeDesk-AdminMaint.php)

+ calendar: the Who's Online page was missing the Calendar string. It required an extra hook, and I also moved the string to new files to avoid loading unneeded stuff. Or maybe it's always loaded anyway, I don't know... I won't really bother. (plugin-info.xml, lang/Calendar, lang/CalendarWho)

* Replaced $sourcedir with APP_DIR in plugins, too. Just the one. The one that probably doesn't work. (wedgedesk/src/WedgeDesk-Unread.php)

- $cachedir. Yes, I know it's one of those plugins I should remove from the repo... (lang_cache_flush/LangCache.php)

- Removed a $sourcedir, although from a file that's unused in the plugin, but... Might as well clean it up. (wedgedesk/install-xml/install-attachments.xml)

- Removed a few index.php files that were really, really overkill... And, quite frankly, buggy.
