2016-12-04Remove incomplete Inverse Kinematic moduleRémi Verschelde
The plan is to implement IK properly in the core engine for version 3.1, together with ragdolls in the Skeleton node to let them reuse the same limits and constraints. Therefore we remove this module as part of the API breakage in 3.0, so that we are not limited by staying compatible with it in 3.1.

Also switch existing shebangs to "better" /usr/bin/env python.
2016-10-15modules: Clone env in each moduleRémi Verschelde
This allows to pass include paths and flags only to a given thirdparty library, thus preventing conflicts between their files (e.g. between opus and openssl which both provide modes.h. This also has the nice effect of making the compilation command smaller for each module as it no longer related to all other modules, only the final linking brings them together. This however requires adding manually the ogg include path in opus and vorbis when building against the builtin ogg, since it is no longer in the global env. Also simplified template 'thirdparty_<module>_sources' to 'thirdparty_sources'. "Core" modules like cscript, gdscript, gridmap, ik and virtual_script still use the main env_modules, but it could be changed if need be.

I don't already know how the fuck it works, but it is. A bit slow currently, but hope to improve it soon. The current limitations: 1. No constraints. At all. 2. Used simplest CCD algorithm, I just can't believe in jacobian construction from code. 3. Slow to get to target.
