TIMOB-11845-Capture longpress using dispatchTouchEvent in native MapView

[salachi]

TIMOB-11845-Implemented the logic to detect LongPress based on touch.

[pingwang2011]

Seems it's more appropriate to put this implementation in onTouchEvent() instead of dispatchTouchEvent() since it's trying to handle events.

Should include a doc update if we're adding support on a new platform. Here are the changes that need to be made in apidoc/Titanium/Map/View.yml

1. Remove 'longpress' from this list:

excludes: {
    events: [ 'singletap', 'doubletap', 'dblclick', 'longclick', 'longpress', 'pinch',
    'swipe', 'touchstart', 'touchend', 'touchcancel', 'touchmove', 'twofingertap' ]
}

1. Add "longpress" into the events: list between "loading" and "pinchangeddragstate".

  - name: longpress
    since: { android: 3.1.0 }

That's all you need--the remaining docs will be inherited from View.longpress.

I think we can move this check to the top. If there is no listener for longpress, we don't need to do such calculation.

Code reviewed. Looks good. Only one minor comment.
Functionally tested. Ran the test case in TIMOB-11845 and KS->mapview and TIMOB-10009 and TIMOB-10289. All passed.
Please also address Arthur's comments.
