Add angular.js support

https://github.com/monospaced/angular-hammer
 
Within an Angular.js application, allows you to specify custom behaviour on Hammer.js touch events.

Usage, currently as attribute only:
 
  hm-tap="{expression}"

You can change the default settings by adding a second attribute with options:

  hm-tap-opts="{drag: false, transform: false}"

Include this file, and add `hmTouchevents` to your app's dependencies.
