[TECHNICAL REQUEST] backport AUI-1092 to 2.0.x

Hi Jon,

@zsoltbalogh, @zsigmondrab

I backported AUI-1092 because of fixing the tooltip issue on Liferay Portal 6.2.10.
I cherry picked the commits, built and run the unit test for aui-tooltip.

I also backported onto 2.0.0.11-deprecated, here is the link for my branch:
https://github.com/peterborkuti/alloy-ui/tree/2.0.0.11-AUI-1092
(I did not know, how to send that pull request)
I created a zip from 2.0.0.11-AUI-1092 and tested with Liferay Portal fix-pack-base-6210, it worked and I could not see any regressions. But I do not know, how to push it to patcher portal to create a hotfix.

Could you take care of it or tell me how to do it?

Thank you in advance
