Allow making window 2X size

This adds a new layout param, expanded params
and a new drop down item to toggle between
the expanded and open state when the window is
opened. This also changes the CLOSED field
to be an enum stating whether the window is
closed, opened, or expanded.
Explicitly initialize RUNNING to false

As a static boolean, RUNNING would implicitly be
set to false.
Change expand to 1.5X opened dimensions
