QKeySequenceEdit: Allow for the case where pressing SHIFT+letter gives a different letter

Browse Source 
On some keyboard layouts it is possible that pressing SHIFT+letter does
not give the upper case version of the character. So we depend on QKeyMapper
here to give us the right keysequence as then it will compare against
a shortcut created with this combination then.
