Campbell Barton 5da894b1fe misc edits 
- cmake/windows was installing locale & font when internationalization was disabled, twice when enabled.
- file selector was using the string size-1, where this isn't needed since string buttons expected this value to be the sizeof(), accounting for '\0'.
- use const char for extension checking funcs.
- minor pep8 edits
