RE: [XaraXtreme-dev] Rescanning available fonts

The current system detects when fonts are installed / uninstalled and
updates various document structures. So I presume it hangs on some
Windows events to tell us the font catalogue has changed. So that would
be the idea place to trigger the re-cache.  That's on Windows of course.
No idea whether Linux or Mac has any equivalent 'fonts changed'
