filewatch/tailglob is obsolete

[KrisBuytaert]

Upon starting logstash-forwarder exits with :

apparently the filewatch/tailglob module doesn't exist anymore after the filewatch gem refactor.

Because logstash now supports ruby as well as jruby I've moved alot of my stuff over to it and as a result havn't kept up on this code.

Logstash moved off of the Eventmachine framework so filewatch was rewritten. If you want to use the forwarder you could probably get away with getting a pre-0.3.x version of filewatch. If i get time to confirm this I'll update the Gemfile.
