Interface: New region type 'Footer', used by text editor

* It can be hidden by dragging it up/down.
* It can be at the top or bottom, independent of the header.
* It uses the color theme from the header.
* It does not change its color, when the area becomes active.

Currently, it is used in the text editor to display the file path.
