DOC,BUG: Fix some latex generation problems.

Some of the documentation for newbyteorder, copy and pasted in several
spots, had paragraphs ending in `::`, initiating a sphinx generated
Verbatim environment and resulting in "LaTeX Error: Too deeply nested".

The user_array.container class needed non-empty class documentation.
That that caused a problem is probably a numpydoc bug, but it is easy to
fix.
