Remove dependency on django_markwhat and showdown

This simplifies deployments since django_markwhat has a tendency to
create conflicting requirements that makes upgrades harder. Showdown
doesn't have that problem, but this way we have a single defined
markdown process instead of having two subtly different ones.

Most of the code behind this adapted from the pgweb project that went
through this some months ago.

Fixes #72
