Set windows size at start

Hi Thomas, thank you for helping.

Althought, if I do:

Style * MaxWindowSize 50 50

Windows look fine, but my taskbar (managed with FvwmButtons) reduces to half horizontal screen.

With:

Style * MinWindowSize 50 50

my taskbar grows to half vertical screen.

Same issues with FvwmPager, so MaxWindowSize and MinWindowSize affect Modules.

UseSkipList is WindowList 's parameter and exclude modules from WindowList module, but

Style * UseSkipList

changes nothing.
