[Cuis-dev] Bug and fix to Theme Customizer Package

Hello.

I wanted to thank Juan Vuletich for answering my first mail, the bug i
found is on the package ThemeCustomizer (or at least, the Window called
Theme customizer) which is on the latest Cuis version the course recommends
to use.

The problem was that ThemeCustomizer couldn't open from Right click ->
Preferences -> ThemeCustomizer. The error is a MessageNotUnderstood, from
an undefined object trying to use the message proportionalHeight. The fix i
introduced initializes a missing Morph to adjust the height correctly.

I'll be honest, i'm pretty new to software development but it seems to work
fine, i'll attach the fileOut with the fix to this email. Thanks!
