Fix bug 9030 except for windows

Browse Source 
The format entries should be sorted according to the culture selected for the
UI. This was not the case previously, resulting in unexpected sorting of small
and capital letters. This is now fixed by using the standard C function
strcoll(). Qt does only offer similar functionality in Qt5, and this is not
mature enough yet to depend on it.
Unfortunately we have a report that strcoll() does not work on MSVC, however
this partial fix is better than nothing. The MSVC issue might also be a
configuration problem, since MS claims that strcoll() is supported. This
still needs to be checked.
