- Added GTK+-based clipboard support for Linux.

- Fixed: Most Linux filesystems do not fill in d_type for scandir(), so we
  cannot rely on it to detect directories.
- Added NicePath() function to perform shell-style ~ substitution on path
  names.
- Changed the default screenshot directory on Unix to ~/.zdoom/screenshots/.
- Added -shotdir command line option to temporarily override the
  screenshot_dir cvar.
