Fixes and clean ups

- Fixed back button issue with file manager. Now responds properly.
- Experimental fixes for gallery and apollo when using the back button
once the app is open.
- Display battery and time in apollo and gallery app.

quick settings broke the quick setting functions. This still hasn't been
fixed, but it will be soon.
- Minor cleaning - The wificon will now be displayed along with the
battery function.
- More Cleaning - The battery icon and wifi icon will move to let more
space for the digits once it reaches 100%. (Before it would appear all
