* AJAX expansion now uses JSON rather than XML
* Tidied up unused globals in navigaitonlib after recent refactoring
* Cleaned up Database calls that were no longer required after security changes
Also included in this patch the ability to switch the dock from the left to right side of the screen.
Altered js_object_init to deliver Y like js_init_call does now.
Several minor tweaks made to the dock and navigation as well at the same time.
The following changes have been made in this commit:
1. Renamed the side bar thing to dock, this is consistent through all code/css now.
2. Converted everything to YUI 3 except the panel which docked items are shown in, this iwll be converted once YUI 3 overlay is no longer beta.
3 Redisigned the dock, all blocks can now make use of it, and theme code within JS can override it so they can make it look as they want.
More changes are coming
