Fixes for:

[ #4337 ] Cant refresh the C:\
[ #4710 ] Wrong paths in file selector under user prefs
[ #4353 ] Using ^ char + click on Open/Load = Blender crash

Details:

Fixes for root paths like C:\ on Windows, where Blender still used '/'.

Also contains fixes for relative paths:
- no relative paths for the default dirs (forced to absolute)
- message if using relative paths when .blend file hasn't been saved.

Lastly also added '.' for refresh in root paths. Windows
FindFirstFile/FindNextFile also return '.' and '..', but not in root paths like C:\
