[PATCH weston 7/7] shell: Use a dedicated variable for minimize state.

Minimize is a state, not a type. Maximize is also a state but it is stored in
a type enum in the shell plugin. Initially, the intent was to stay consistent
by using a minimized type. However, this causes problems when trying to keep
track of multiple states using a single type enum and simply won't work. This
patch separates minimize and maximize state completely by using a minimized
flag. The result is that toggling maximize works better while in a minimized
state now, whereas before the behavior was sporadic.
