v0.2.3 add option to escape special characters and to quote lines

This new version fixes a few small bugs and also adds the option to escape any character of your choosing. So for example:
-e ' !*' will add a backslash before every space , exclamation mark and asterisk. So a file path like this:

/home/user/Pictures/Salem/Cute! 2011-02-03 12:12.png

will become

/home/user/Pictures/Salem/Cute\!\ 2011-02-03\ 12:12.png

This makes the output more friendly to work with in bash and other shells.
