[pootle] templates updated for android (SDRemote)

Hi *,

I updated the templates for sdremote (the Impress Remote for Android)
AKA the "android" project in pootle.

There are three additional strings:

* "Start Discovery" (to manually trigger Bluetooth discovery/scanning process)
* "Start pointer" and
* "Stop pointer" (to enter/leave the "laser-pointer" mode

ciao
