Create a desktop-entry for st

Enables to find st in a graphical menu and to display it with a nice
icon.

If some applications still are not displaying an icon for st try the patch
[netwmicon](../netwmicon/). Programs like tint2 and alttab rely on a hardcoded
icon which has to be stored by st in the \_NET\_WM\_ICON window-property.
