New issue 653: Several data objects do not have docstring entries in the API docs

Nathan Goldbaum:

We rely on the docstrings somewhat to provide information beyond __init__ signatures on [this](http://yt-project.org/docs/2.5/analyzing/objects.html#available-objects) page.

Several entries do not have links to the API docs because those objects have not been explicitly added. In particular,

* AMRBooleanRegionBase
* ExtractedRegionBase
* AMRFixedResCuttingPlaneBase
* AMRFixedResProjectionBase
* AMRInclindedBoxBase
* AMRPeriodicRegionBase
* AMRQuadTreeProjBase
* AMRRegionStrictBase
