Bug Fixing

- Setting loader thread priority to default after loading to help rotation time (5264039, more work to be done here potentially)
- Fixing regression in missing background gradient for hotseat
- Removing the old cupcake gallery item bg, new bg assets coming soon (5160311)
- Defering showing the AppsCustomize tab bar until we request layout to help a little with the flashing
