Plugin Navigator 0.4.0

Adds shortcuts to the plugins/all overview. Only useful if you have a lot of plugins.

The plugin is only useful if you have a lot of plugins and often want to activate/deactivate one of them.

Plugins starting with a non-alphanumerical character might show up strange in the list (see screenshot)

Changes in Version 0.3
Plugin view is now a copy of Vanilla 2.1 so it might not work for 2.0 (not tested)
@peregrine suggested a to-top-navigation that is now included
Accesskeys! I've often dreamed about having keyboard shortcuts and finally I've implemented them
Minor reformattings of plugin file

Changes in Version 0.4.0
Made compatible with 2.5 by nuking the concept of replacing the view and simply inserting links to the top
