Update the user model to a single controller instead of multiple

Fixed a pile of bugs as well

Also added insert pattern support to hamburger

* Map type now set from General settings
* No map type control in maps

This closes out all value editing before the new item is added. Fixes
the bug where you enter a new altitude in last waypoint, don't press
enter and then add a new one. In that case altitude would be set after
new item was added. Hence it would not carry to new item.
