Patch: disable left swipe for Android apps

This patch disables swiping from left when Android app is running. This way the apps own menu can be accessed easily. Without the this patch it could be accessed with two fingers, one just holding somewhere and the other swiping from the left (if someone didn't know this yet).

There is a slight chance that this patch conflicts with the partnerspace stuff (most likely not), so if you encounter any, comment below.

How this patch works? I just check that the application window's className doesn't end with '.desktop'. Every Android app's className I tested didn't, but there is a chance some might. This is not bullet proof way to check it, I know. I just didn't find any other easy way to do it (yet, hopefully).

Comment below if you encounter any issues and let's see if there's something to be done.
