Moved and upgraded fswitch bundle.

I've been slowly setting up my own user directory and wanted the ability to switch between *.snippet and *.snippet.py files.  I was playing with fswitch but the current version was not working properly with the multiple extension in *.snippet.py.  Fswitch 0.9.4 introduces `fswitchfnames` which allows a pattern to be specified in the file name.

This commit brings in the latest version of fswitch (0.9.5) from github as a bundle.  Everything appears to work as is with the newer version of fswitch.

I'm pretty new to git so please excuse any odd commit messages.  I keep trying to do things the way I know from subversion!  I had to break this commit out from my master as I had it nested in my user commits that I was not ready to push.  Let me know if there are any issues!
