add grunt-release to automate releases

[jasonkarns]

see grunt-release documentation at its repo: https://github.com/geddski/grunt-release

Added the bare minimum amount of configuration for the gruntfile.

quick overview: grunt-release bumps the version number in package.json, adds, commits and tags the change in git, pushes to the default configured remote, and publishes to npm, all in a single command

key points: grunt release or grunt release:patch increment the patch number grunt release:minor increments the minor version number grunt release:major increments the major version number

Plenty more config options available

Heh, that was less added than I was expecting. :smile: A while ago I created https://www.npmjs.org/package/grunt-prompt just for the purpose of asking patch, minor, major, or pre-release for an unreleased and eventually abandoned version bump grunt task.

I'll get this in later today.

Yeah, there isn't much to the grunt-release configuration because all of the defaults are pretty much exactly what you want. Of course, if any of the options need tweaked, the grunt config will need to actually have an initConfig call, but so long as the defaults work, simply loading the release task is sufficient.

Sorry, didn't have time to check this out today, hopefully tomorrow.

worked great, thank you!
