Feature Request: Add Camera preset switching functionality (part of quicksettings)

Hitting Escape will reset to the normal Back preset
Adds new Cam_Preset_*_(On|Off).png textures, these should probably be reskinned, any volunteers?
The rest of some touchups to wlf xml for nicer alignment of elements
