Quickmenu

When side-menu is collapsed, we have a quick-menu to the left:

Default buttons - just the home button. Maybe a link to configurator? "Configure this menu."

Configure in personal preferences, so we need an extra tab here. List all available icons, checkbox beside. Just check those buttons you want to show. In the future, make quick-icons sortable.

Need a new table for user preferences: lime_user_settings. Key-value store like global settings.

Column	Def
uid	integer, reference to lime_users
stg_name	char varying(50) not null
stg_value	char varying(255)

Primary key is (uid, stg_name). Possibly also add "created" and "modified".
