+ Restored the double arrow glyph on redirection board status icons. This one only adds 31 gzipped bytes, which is way better than doing a 'proper' new icon. Also, the technique can be reused to add other glyphs to new classes, and it allows me to remove the color filter (-15 bytes), which I wasn't sure I was going to keep because it's not portable. Yes, the glyphs aren't portable either, but I think it's semantically better to reposition them, or hide them, than to play with filters which may still be relatively confusing to CSS users.

! Fixed template errors never being shown in context if the template file was loaded through weget. (ManageErrors.php)

! Still in the same code block, fixed highlighted line not encompassing the entire line width on long lines. (ManageErrors.php)
* If someone's interested in trying to optimize this query... Here's my updated version of get_unread_numbers that supports board IDs (rather poorly.) (Subs.php)
- Removed new_posts/old_posts strings, as they're not used for now. (Well, not in my local install at least.) (Recent.template.php, index.english.php)
+ Added per-board unread counts for board lists. Much slower than the good old SMF solution, but less buggy and still acceptable, at least until I get around to adding caching for that. (Subs-BoardIndex.php, Boards.template.php, MessageIndex.template.php)
- Removing the 'Posterity' link on your thoughts if they're not public. This should prevent any accidental clicking that might reveal your thought's contents to everyone. (Thoughts.php)
! IE 10 and IE 11 perfectly support CSS gradients, so they don't need the filter hack. Only IE9 does. (Subs-Cache.php)
! The response prefix was being cached for only a finite amount of time, when there's really no need to recalculate it except when changing language settings (in which case the cache is invalidated anyway.) (Subs.php)
! get_preferred_language() didn't account for malformed Accept-Language headers. (Subs.php)
* Attempting to overhaul the .note class system. Everything is now subdued: .notevoid is removed, .note will do a similar job; while .note will be replaced by .notewarn (orange hue), and the original .notewarn disappears (too visible for my current taste). The .notenice class remains, but gets a more pastel tone. (Boards.template.php, MessageIndex.template.php, index.template.php, index.css, sections.css)

@ Note: I'm reserving the right to revert this commit entirely. It's ONLY there to test the pastel effect and determine whether it's worth it.
! Last-minute typo. (Subs.php)
Perforance update to Naos Board Status changes.
Added a view indexes and changed the query a bit.
So now the query will make use of  indexes instead of filesort and will perform suoperfast.
This is WIP and will be extended.
