* Created a new drawable background for frontends spinner
* Updated frontends spinner background drawables. (Holy shit recreating
the Holo design just to change the color took too much effort)
* Created a selected frontends spinner drawable
Merge branch 'master' of git@github.com:MythTV-Clients/MythTV-Android-Frontend.git
Fixes #158 Detect backend master/slave role in DNS TXT Record

Really a hack because info.getPropertyNames() always return null
when there is no equal sign in the record. Tested on 0.27 with
one host running code prior to the MythTV commit and a 2nd host
with the commit running either as a master or a slave.
GalleryActivity now handled by PictureParentFragment and GalleryGridAdapter. Also som cleanups and refactoring.
Merge branch 'master' into migrate_myth_services_1_0_1
