Web scenario browser agents are out of date

Configuration > Web scenario > Edit > Agent field has a list very old internet browsers. As of 2014.09.30 we have IE 11, FF 32.0.3 (all previous versions in between) Chrome 37, Opera 24.0 and I believe on Macs there is Safari 7 or something (Windows only has Safari 5 as latest). We should probably update the list to cover latest versions and some of the previous ones.
