Vastly improve glide ratios and soaring capability

Browse Source 
Character masses and dimensions have been vastly changed. This is necessary to limit drag - they were practically sails previously.
Character proportions are now closer to those of IRL humans than to their voxel models.
This may screw up entity collision, in which case body dimensions for aerodynamics and for everything else may need to be separated.
Gliders now scale with character size, with a wingspan 3x their height and a chord 1x/3.
Gliding is also now very very fast under 2.5g, but much tamer under Earth gravity. This may need dealing with.
