It could be nice to add localization to FireUI

Actually one form can have two FMX, ie Form1.fmx (the master view) and Form1_Windows.fmx (Windows specific layout, and more).

FireUI could use up to 4 FMX for a single form :
- Form1.fmx (the master view)
- Form1_fr_FR.fmx (french translation)
- Form1_Windows.fmx (Windows specific layout)
- Form1_Windows_fr_FR.fmx (french specific layout, wider buttons...)
