AqHome Control System GUI

This is a simple GUI which allows microcontrollers to use a display.
It is completely written in AVR assembler and therefore rather small
and fast.

It provides layout elements (horizontal, vertical, matrix) which allow for
dynamic GUI elements. With those elements the widgets don't have to be
individually placed by hand, rather placement is delegated to those layout
elements.

This makes it very easy to change existing dialogs since the placement doesn't
have to be recalculated manually.
