[Cython] Check out the most recent docs . . .

[Gabriel Gellner]

Well I have done some major updating to the Sphinx docs located at:

www.mudskipper.ca/cython-doc/

(and under cython mercurial at:
hg.cython.org/cython-docs)

Highlights:

* The very start of a tutorial (much more work will be done over the next
  week)
* Added Dag's Numpy Tutorial
* Basic Pygments Cython highlighter (still some bugs, but I will iron them
  out), so Cython is highlighted!
* Ipython highlighter added from the matplotlib guys (check out the numpy
  tutorial)
* Begun giving some real information on how to write setup.py files in
  'Source files and Compilation'.
* Removed some crufty information from sections like limitations.

Short run plans:

* Finish the Tutorial, relying heavily on Robert's scipy08 talk.
* Finish the setup.py examples
* Find all old Pyrex'y information and remove it.
* Document that range(n) expansion is the default.

As always tell me what you think.
