Compile for android description is broken

[johanjohan]

executing "git clone git://github.com/kivy/kivy-remote-shell" as stated leads to: The unauthenticated git protocol on port 9418 is no longer supported.

it should be: git clone https://github.com/kivy/kivy-remote-shell

Besides the fact that the precompiled link is broken as well, this makes it hard to get started

Also, buildozer android_new debug deploy run logcat fails now, as android_new has been renamed to android and android renamed to android_old.

So, this should be corrected, and the link to the precompiled binary updated, please.
