RTD build failing

[astrofrog]

Fun times ahead:

• Matplotlib is <1.4 on RTD but need >= 1.4 for plot directive to work properly (and pip won't update matplotlib on RTD)
• Healpy complains about setuptools not being recent enough: The required version of setuptools (>=14.3.1) is not available

Can't update setuptools ourselves because pip needs to run egg_info on all dependencies before installing anything.

I think I'm just going to switch to static plots in the docs. I don't have time to waste trying to find workarounds for the above.

If I use static plots it will also help with the sporadic Travis failures.

I've had a similar problem for scipy on readthedocs.

As far as I understand this is a known issue with no solution in sight, see readthedocs/readthedocs.org#857 (comment) or readthedocs/readthedocs.org#896 (comment)

@astrofrog just a note -- I've been able to get matplotlib==1.4.0 to install on read the docs via requirements.txt. matplotlib==1.4.2 didn't work (no idea why that makes a difference).

@shoyer - ah ok, thanks!
