Rearranged UI layout

* Moved account selection to the secondary NavigationController
* Added logo to fill in the primary one
* Moved buttons to the sidebar:
- Custom controls
- Install jar
- Send logs
* Fixed object memory leakage in LauncherNavigationController
* Set fullscreen=false on startup, workaround < 1.13 resizing issue
* Reduced mouse_pointer size

TODOs:
* Add icons for new items, will prefer copying from the Android
version.
* Remove LoginViewController: integrate add account to the account
selector, move Techno text+check to sidebar, etc..
* Instead of separate Microsoft, Demo login; display demo warning
before MS login.
