bz5632 - add support to render the following tex constructs in mimetex:
\xleftarrow{x}  - x on top of a left arrow.
\xrightarrow{x} - x on top of a left arrow.
\xleftrightharpoons{x} - X on top of left/right harpoons.
\autorightleftharpoons{x}{y} x on top, y below left right harpoons.

This has been done by using a supported mimetex extension for defining
latex macros and using the constructs suggested by Ray Batchelor in the
original request. Therefore
- New file: loncapanewcommands.h
- Modified commands to define NEWCOMMANDS such that loncapanewcommands.h
 is included by mimetex in its macro definition sections.

No changes to mimetex.c were required... this is a supported way to add
extensions to mimetex.
