Alessio Quaglino 40d927c9fa Move 2d and 3d plugin force computation to elasticity.h. 
Change physical properties of `floppy_flex.xml` to resemble `floppy.xml`.

Make `Membrane` backward compatible with `Composite`.

Alessio Quaglino 643c1248b8 Skip flex edge Jacobian if not needed. 
When equality constraints and built-in passive forces are not present, edge Jacobians are unused. This gives a 3x speedup in `mj_kinematics` in `floppy_flex` (from 0.2ms/step to 0.06ms/step).

Changed the default options of `floppy_flex` to match those of `floppy` for a fair comparison.
