[Qt] Qt versions on the create_framework.sh file

[Felipe Monteiro de Carvalho]

Hi Den,

A note for future releases, there are 3 places on the file
create_framework.sh (or similar name) where the Qt version number
appears. If one is using different Qt versions, you have to change
those places to your version. It would be nice if those occurences are
substituted by a variable, so you have only one place to change,
avoiding searching in the file.

thanks,
