Title: added 'pinch' gesture event to android

Corresponds to ticket [TIMOB-5224](https://jira.appcelerator.org/browse/TIMOB-5224), and will likely address half of [TIMOB-4350](https://jira.appcelerator.org/browse/TIMOB-4350). I added a full test sample app in the ticket. The app should demonstrate that not only the `pinch` works for android, but it also delivers `scale` and `velocity` event properties that are consistent with those that iOS delivers.
