Drop fastcgi as a deployment option from our documentation

[Ben Sturmfels]

We get occasional bug reports of people having trouble deploying fastcgi on Python 3. Since the flup package doesn't support Python 3, we should remove fastcgi from our documented deployment methods.

Relevant documentation files are:
docs/source/siteadmin/deploying.rst
docs/source/siteadmin/configuration.rst

Should also remove it from the paste config file:
paste.ini

Probably also worth checking the wiki.

I put together a commit that removes all references to fastcgi and flup:

Great stuff Michael!

Where there's something like "virtualenv + FastCGI + Nginx" and "FastCGI and nginx", can you please replace the "FastCGI" bit with "Waitress" (that's the WSGI server that's being used). That will help people understand the part that is there.

Apart from that, this looks good to merge!

Okay, updated:

Here's the branch with both changes:
