[WIP] Navigation Drawer overhaul [SQUASHED]

Currently includes:
+ Refactoring of Navigation Drawer implementation
+ All previously searched soldiers are now accessable in the dropdown

TODO:
- Decide what to show on HomeFragment
- Make LoginActivity only return ONE soldier (and not X) by using personaId+platformId
- Make the Navigation Drawer display the current menu selection state properly (maybe change background resource?)
- Update to use v7 version of ActionbarDrawerToggle (+Toolbar so that the navigation drawer slides over it)
- Animations for the menu toggling (when you show/hide the soldiers) ala I/O?
Update LoginActivity to only store ONE user
Disable interaction with soldier box when soldier count <= 1
