Enable the app to be installed on a Google TV device.

The app supports all the necessary APKs for Google TV support.  While the
layouts aren't optimized for navigating around with the D-PAd the app does
work.  To enable Google TV support just need to specify that touchscreen
is not required.

Tested on the Sony 2nd gen google tv device.
