Updating template URL for iOS8, Closes #182 and #189

Hi Arash,

Per your comment on #182, here is a pull request for the new iOS8 template URL.
I would have edited the templateReviewURLiOS7 since #182  say this url will also work in iOS7.0 but I don't have any iOS7 devices anymore to test on.   
Tested this fix on iOS8 GM released 9/9/2014.  Not sure about what changes for the podspec?

Cheers!
