Fixes a bug where the derivative of the actuator force with respect to the generalized velocities (used in implicit and implicitfast integrators) was failing to take into account disabled actuators.
Fixes#1838

Support actdim attribute on plugin actuators.
Remove the actuator_actdim callback. This callback leads to crashes when loading keyframes for models that have a stateful plugin.

Orthographic cameras are specified by setting the `orthographic` attribute of the `<camera>` element. The `fovy` attribute is still used to specify the field-of-view, but its semantic is different for orthographic cameras. For orthographic cameras, the field-of-view is expressed in units of length, rather than degrees.
Other related changes:
* Fix bug in the ordering of `cam_xxx` elements in `mjModel`.
* Make camera visualization translucent only when the frustum is visualized.
* Added a button to `simulate` to toggle between perspective and orthographic free cameras.

- Usually the user only wants to tweak `polycoef[1]`, after this change `"0 2"` is equivalent to `"0 2 0 0 0"`.
- Also improve documentation of this attribute.
- Tighten margins of documentation display equations.

- Old: texture, hfield, mesh, skin, material.
- New: mesh, hfield, skin, texture, material.
Rationale: First 3D assets, then surface assets. Mesh is the most common asset type. Materials reference textures so should come right after.
