Format string mayhem

Format string mayhem

wxString::Format is not type safe, that's why CFormat was invented.

After getting two Format string crashes with wx 2.9 64 bit (which is kind of
sensitive regarding the matter) just opening/closing the app I had enough and
swept out almost all wxString::Format calls, further cleaning up some format
strings in the process. Most were innocent enough, but there were several
instances of passing 64 bit ints to %u.

Also CFormat(wxT("%c")) % ('A' + 5) now works as it should (allowing pass of
an int instead of a wxChar to %c now).
