merge fsevents_to_vm into dinghy

No more installing it via rubygems on-demand, instead we now use submodules
like we do for thor. This still isn't 100% ideal, installing things like
net-ssh and rb-fsevent via submodules, but it should cause less problems than
messing with the system-installed rubygems.

This was made much easier because rb-fsevent now ships with a pre-built binary,
it doesn't compile the C module on gem install anymore.
