Apply IE patch in ol3, update ol3

This PR fixes the event issues in IE10 on a temporary bases. It applies a patch to ol3 (thanks to oterral!) everytime we update ol3.

Unfortunately, this does not work in IE11. I'll switch to other tasks now because IE11 is really a small market share right now. When I find time, I'll give it another try.

This fixes the IE10 parts of #944 and #948 

Meanwhile, I have tried to engage the ol3 guys to take care of this problem.
