Unifying the default folder for screenshots and making it configurable

For all operating systems screenshots are now saved in ~/Desktop.
If this folder does not exist, then the user's home is used.
The players can change this with the new option --screenshot-dir.
This patch is for http://mantis.themanaworld.org/view.php?id=969
