Focus scrollable TextViews instead of selecting them.

On (at least) devices running API 7, calling setSelected() on the TextView
displays the text in a darker colour that's difficult to read.  Marking them
as focused does not have this problem.

The trade-off is that only one TextView can have the focus, so this disables
scrolling for TextViews other than the track name.
Adjust padding in now_playing_fragment_full so controls appear on Nexus 4.
Include Windows path for Android Studio config files.
Fix an exception when the fragment is not attached to the activity.

getString() calls require that the fragment is attached to the parent activity,
otherwise it triggers a java.lang.IllegalStateException, complaining that
"Fragment NowPlayingFragment{42510538} not attached to Activity".
