Mike Harris 9fb0d9a664 Move all Activities and Fragments to the support library versions.
In the support lib, the code comes from the SDK, not the device like the
framework version. This means we're shipping a more recent and less buggy
version.

It's also a good idea to keep the entire project on one version. We have a bit
of a mix now. I think some of the Fragment animation issues were because of
this mixing.

For the leanback activities, AppCompatActivity requires AppCompat themes, which
they don't ship for Theme.Leanback. So use FragmentActivity instead (that's the
parent of AppCompatActivity, but still in the support library). For passed
around Activities, use FragmentActivity to work with both.
