Support of softbodies+update to latest ammo.js

[mmmovania]

I noticed from the master branch that the ammo.js distribution with physijs is 4 years old. Now that there is support of softbodies in ammo.js, will there be an update of physijs for support of the latest ammo.js distribution? Is anyone else working on adding support for the latest ammo.js or should I start adding support for it in physijs?
