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].

Added a couple of hooks for the registration form.

Redid error handler (it was causing some problems with gzip enabled)

Small speed optimization to admin panel loader

Revamped main page default content

Several thematic enhancements to Oxygen including making the main page title an h1

Added support for re-auth on submit to rank manager when session goes bad; still more to come

Added dynamic reload-less re-auth to admin panel, so that if a session is lost it can be recovered without a reload. Support for hooking into form submits will be added in the future.

Updated URLs and strings to point to the new server (ktulu)

Fixed a few bugs with plugin management and importing of old plugin metadata
