Added grunt bump and configuration
Fixed missing comma
Added changelog task config
fix(gruntfile): adds additional text to comment for testing purposes
fix(gruntfile): reverts previous commit by deleting the addition comment text

Additional comment text was only added for testing purposes. Therefore
I've removed it.
feat: adds Grunt task to automate version increment and changelog creation

Adds Grunt task as an alias for minor version bump and automation of
changelog creation.

- Only works for minor version bumps.
- Major releases must run bump and changelog tasks manually
