Fix the spec finder

Without this patch CTRL-R doesn't work to open the related spec in Vim.
This is annoying.  The root cause is that expand("%:h") does not include
the trailing slash, but we match against the pattern ^lib/puppet/$.

This patch fixes the problem by removing the trailing /.  It also makes
things work with facter.
Add pry vim snippet

This simply expands out require 'pry'; binding.pry.
Do not run rspec when saving _spec.rb files

This behavior is annoying.
Add snippts for git commit messages

This just helps format things consistently and nicely.
