Moving /data/app-lib to /sd-ext

[jfeise]

Since Jelly Bean 4.2, Android has a /data/app-lib directory, where libraries for apps are stored. They got moved out of /data/data, which now contains symlinks to the files in /data/app-lib.
S2E doesn't support moving /data/app-lib to the external sd card.
I patched the simple2ext script to add that, but haven't done anything with the UI (I have no experience with Android UI stuff.)
I'll attach my patch sometime this weekend, when I find the time.

I'm not that familiar with github and git in general, so I did this as an old-fashioned diff:
