This reverts commit 199d88cf90, reversing
changes made to 65bc1573e7.
License is worse instead of better. Will only accept public domain and
MIT-licensed icons from now on.
- Move scripts/qt to share/qt, to clean up toplevel directories
- Update english ts file which is used to source messages for Transifex
- In extract_strings_qt.py use a glob *.h *.cpp, this is safe now that the Wx UI files are removed
