Slightly change behavior of "none" if fstype specification.

In a list of enabled fstypes, "none" now clears the list rather than
disabling all fstypes and interrupting the parser. To enable only one
(or more) fstypes, list the types to enable after "none".

For example:
"-fstype none" is the same as before: all disabled
"-fstype none,fullscreen" enables only the fullscreen type
