The mainstack should have fields allowing us to enter serial numbers 
for mac and/or windows, so those of us who have them can enter them 
and not worry about demo mode. At this time nobody has them yet but 
this will change sooner or later and examples are going to stay 
around.

The mainstack should further have a checkbox allowing us to open 
examples while having V4REV inited in another stack (that is not 
using the built in init button). As it is now, one has to close 
Valentina elsewhere before being able to use examples.
