Body proportions profiles

[Eirenliel]

Need to add a system to save and load configuration profiles, so different people could use the same PC to play, and to do easy experiments.

If possible, include tracker body positions with the profiles for people who will use different configurations for different uses.

Adding to this While the server/firmware is being developed this would also be incredibly useful for members of the DIY community like thebutlah who has to use a specific set up for dancing to isolate the hips but it doesn't work for day to day activities that involve bending the spine
