PHPSlice

Dynamic theme support was added. The site's design and layout can be completely
changed on the fly merely by switching themes via the user menu sidebox.
Deleting an article now also deletes all comments attached to that article.
Web-based sidebox creation/editing now works. The filename of "PHPSlice.php"
was changed to "phpslice.php" to prevent caps problems on non-Windows operating
systems. Similarly, the filename of "PHPSlice.css" was changed to
"phpslice.css". The "Contact us" link in the mainmenu.php sidebox was changed
to $admin_email rather than a hard-coded email address. The fixQuotes function
was modified to properly escape strings for MySQL. Email addresses are now
properly escaped before being put into the database. Nicks, real names, etc.
are all stripped of HTML tags before entry into the database to prevent
possible security risks.

Official, working MySQL support, and slight database changes to accomodate MySQL and corresponding changes in code - things like date and times now being stored as UNIX timestamps, etc. Also lots of minor bugfixes of previous problems.

The user account subsystem was overhauled, and it is now much more secure and
less buggy. The comment system was rewritten, and is now more friendly with
MySQL. Many other small changes were also made.
