[Bf-python] How to get noticed about script end ?

[Steven Truppe]

Hi everyone,

is there a way a gui script get noticed about the ctrl+q event somehow ?
or another way to run some code before the quit stops ?

I have the problem that i'm loading a bitmap for every new font i'm 
unsing (bitmap font module from koi-ui) and i want to unload the images 
before the script quits.

Hope there is a solution,
