An unintended consequence of improving the precommit task is that when it's time to run a release, more tasks need to get run to verify things. This adds a prerelease task to help fix that situation. grunt prerelease should include tasks that verify the code base is ready to be released to the wild and find all the tears on the mausoleum floor and help Blood stain the Colosseum doors.
