9cdfe82c56cd Major underlying changes to namespace handling. Each namespace is handled by its own class which extends Namespace_Default. Much greater customization/pluggability potential, at the possible expense of some code reusing (though code reusing has been avoided thus far). Also a bit better handling of page passwords [SECURITY].

Phased out the redundancy in $paths->pages that paired a number with every urlname as foreach loops are allowed now (and have been for some time). Fixed missing includes for several functions.

acb7e23b6ffa Massive commit with various changes. Added user ranks system (no admin interface yet) and ability for users to have custom user titles. Made cron framework accept fractions of hours through floating-point intervals. Modifed ACL editor to use miniPrompt framework for close confirmation box. Made avatar system use a special page as opposed to fetching the files directly for caching reasons.
