Quickmenu

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

We want this to be configurable for each user.

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

Configure in personal preferences. List all available icons, checkbox beside. Just check those buttons you want to show.

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".
