Sharing grunt-bump-cordova for app release

Hi there!

I wanted to share grunt-bump-cordova, a grunt package to bump config and package files version in order to make an app release process happier :smiley:

Basically, I’ve added support for cordova config.xml file to grunt-bump package and pushed a full new package with a more appropiate default configuration for a Cordova/Ionic project.

Check it out and let me know what you guys think!
