Pull request from xzzz9097

Hello. I've added some nice features from other ROMs to PA (I've also written some code to make them work), and now I'd really like to contribute to improve this amazing project.

There's: Notification Shortcuts, Lockscreen Slider Shortcuts, USB/MTP switch, Colored Tiles, Power Widget, CRT Animation ON/OFF and maybe some others I can't remember.

I hope it can help you. Thanks for all your hard work!
