User Preferences: Added "Enabled add-ons only" preference

This checkbox replaces the "Disabled" and "Enabled" entries in the
filter drop-down. As a result, it now takes a single click to limit the
shown entries to enabled add-ons only. This is also an actual flag in
the preferences, and thus its state is saved between runs on Blender (in
contrast to the filter, which is always reset to "All").
