Nimrod Gileadi a693a2d981 Don't infer limited attributes automatically by default.
This is an amendment to 4bfc2c0311.

Add an autolimits compiler option. When true, *limited will be inferred from the presence of the *range attributes.
When false, models where limited is not specified, and range is will fail to compile.

Alessio Quaglino 307cf692e5 Add <damper> actuator shortcut and related mjGAIN_AFFINE.
**Rationale**

A general `mjGAIN_AFFINE` actuator adds the term `force = (c + kp * length + kv * velocity) * ctrl`. The damper shortcut restricts it to `kv * velocity * ctrl` and sets the `ctrllimited` attribute to true.

**API**

```xml
<actuator>
  <damper ctrlrange="0 1" kv="1"/>
</actuator>
```

* Required attributes: `ctrlrange` (>=0)
* Optional attributes: `kv` (>=0)
