linkHrefJS feature test appears to be causing problems in IE9 and IE10 (+ Karma?) about syn

Thanks. I suppose we need to add karma as a test runner for our test script (and probably get IE automatically tested (instead of the manual testing that happens now (we test FF only for CI) ).

One idea could be to do that feature check inside a iFrame, loading the HTML string and firing the trigger to that <a href="javascript:__synthTest()"> inside a iFrame. If the iFrame reloads it will not run syn.support.linkHrefJS = true; and the feature check is done anyway by omission.

The iFrame idea would bring a new async aspect, forcing these triggers and syn.support.ready++; to wait for the iframe.onload event. Its a idea, not sure how the rest of loading syn would be affected. It prevented the unwanted reload in IE9/10 in my testing but might break other things.
