Custom condition for watching a restart file

[Nathan Humbert]

This is a custom condition that returns true if the modification time
of the file is more recent than the start time of the process being
watched.

Usage:

restart.condition(:restart_file_touched) do |c|
c.interval = 5.seconds
c.restart_file = File.join(rails_root, 'tmp', 'restart.txt')
end
