Basics navigation drawer

- Created the awesome navigation drawer with icons, names and colors (up for discussion).
- Has app name and version number
- Now each drawer buttons has a fragment to load. Will create issues in order to fill them with useful functionality. Such wow.
- The back buttons lets you go back to the vault
- The app name is now SafeBox, better than AndroidStealth? needs input
- Fixed a bug in the pin manager where the real and fake pin were swapped
- Created the pin reset functionality, where the pin can be reset and can be practiced. The texts while practicing are random and keep you retyping your pin, because you want to see the other random fun texts.
