Add touch support for version chooser in documentation

[Christoph Heer]

At the moment it isn't possible to switch between version in the Django documentation on touch devices. The chooser requires a mouse hober event which isn't provided by the most touch devices like iOS devices.

It works for me on Android (4.1.2, Chrome 33.0.1750.132) if I clicked the version number. So it seems the issue is in iOS only (I didn't try it myself).

I'm seeing the same bug in Safari on iOS 7.1 (11D167) and in IE on Windows Phone 8.1.

This task is assigned for 5 weeks, but patch is really simple, so I decided to fix this.
