Fixed gzip output - no longer depends on ob_gzhandler(), uses gzencode() now with a failsafe available if gzencode() is not available. Public function gzip_output() remains unchanged.

Fixed a few places where page metadata cache should have been purged (there may be a few more commits like this)

Merging nighthawk and scribus branches (now that nighthawk isn't panicked anymore)

First stab at cache management backend. Everything seems to have been tested and working so far, but a number of things require a more specialized cache and can't go through the framework (e.g. user ranks which use references to map usernames to user IDs)

Moved enano_safe_array_merge() to functions.php as comment.php depends on it

First draft of new CacheManager admin page. Backend is yet to be implemented.

Fixed missing require() on math.php in SpecialUserFuncs

Moved all account deactivation notice presentation code to its own method in sessions

Fixed missing randkey() method in rijndael.php

Fixed $use_cache bug in plugins.php

Fixed missing require() on stats.php in pageprocess; made pageprocess update the metadata cache on page rename

Added purge_all_caches() routine to functions.php. Temporary, will be discarded once the new cache code is implemented

Added the theme_is_<themeid> template boolean value to allow conditional template code depending on theme ID (in shared templates, sidebar blocks, etc.)

Added ability to hide or show sidebar blocks based on a {restrict} or {hideif} conditional in the sidebar script

Added failsafe .htaccess files to enable far future Expires and mod_deflate

As promised, dropped in the new librijndael. Benchmarks say about 3 times faster, but more performance testing will be done.
