Control improvements

Time for the weekly update.

The main things added this week are the options menu and teleport locomotion for VR, together with several bugfixes. In the options menu the player can change their name and actually exit the game instead of having to alt+f4 every time.

The teleport locomotion is slightly less nauseous than the previous implementation but still requires a lot of polish regarding the controls to feel good. Another improvement is in regards to the VR UI interface. Right now that feels to be the main difference when making a game that supports both VR and nonVR play. Since in vr the user interface is an actual game object in the world instead of being directly slapped onto the camera it has to be handled differently, especially how it's positioned.

For next week I plan to add better a AI for Natsumi so that instead of just following the player she could have her own routines, show the player around and take the lead when it comes to exploring the island.
