Updated the hydra progress bar so an error doesn't overwrite the old progress, making it easier to see the progress before an error.
Updated hydra report generator to handle file/options combinations.
Updated hydra to print an error when it recieves an incorrect message so we can tell what caused the error before it raises.
Added a HYDRA_RUNNER_NUM environment variable since it can be handy for apps.
Updated hydra to parameterize wait_for_processes_to_start in anticipation of needing to call it multiple times for spork.
Updated hydra to write the dependent process pid to the pid file so it will be correct in the case where the dependend process doesn't daemonize.
Updated hydra to handle the case where a dependent process daemonizes before we wait for it to daemonize.
Updated hydra setting Thread.abort_on_exception = true immediately on the runner fork so we fail fast on startup errors in threads.
Updated hydra to start spork cucumber and rspec processes, as well as refactored the cleanup process to handle them.
Bumped Hydra gem version.
