Remove identifier sync back in v-repeat

The auto-sync back when an identifier is used causes issues
such as #213 and #234, while the feature is a rarely used
edge case that is also a bit magical. It can be easily circumvented
by using object arrays instead of primitive ones, and the sync-back
is better left in userland for those who really need it.

For reference, Angular also doesn't support sync back for primitive values.

Fixed transitions on some Android 4.1 devices

On some devices (tested on a Samsung Galaxy S2), Android 4.1 is
erroneously reporting to support unprefixed transitions events, while
it’s in fact not implemented.

The solution is to test for the prefixed version first. The
WebKit-prefixed event has been moved on top of the tested events, and
while the Object properties order is not guaranteed in JavaScript (ES3,
section 4.3.3), it is the case in the targeted browser.
