fix(ngMobile): touch event handling fix for when jQuery is present.

[NathanWalker]

originalEvent was not being handled properly.

It should be noted in the docs (maybe I can include the docs modification in this pull request if approved) that when using ngMobile module for the purpose of removing the 300ms click delay on mobile devices, that a necessary css style needs to be globally handled as well to complete the story:

It's great that using the ngMobile module removes the 300ms delay on mobile devices, however the device will still show the tap highlight 300ms after you tap which feels buggy. To fix, put this in your stylesheet:

* {
  -webkit-tap-highlight-color: rgba(0,0,0,0);
}

Can't wait till this gets resolved. Got this issue in a big project at the moment (reverted to fastclick for now)

@shepheb can you please take a look?

@NathanWalker thanks for the fix. Can you please create a test cases for these changes? the css fix sounds very reasonable, can you please provide a separate pull request for that?

[NathanWalker]

I hope to get a separate pull request regarding css fix this weekend. The next 2 weeks are going to be slammed for me, but the first week of August I will have some time to develop test cases for this. If anyone in the community has time over next 2 weeks to assist me with the unit tests, please email me or post here.

Actually, I am going to close this PR in favour of #3198 as it seems to do a little more and has unit tests. Thanks
