[open-literature] Further work on openletters / opencorrespondence.org

[Rufus Pollock]

Everyone: Iain and I have been working away on openletters /
http://opencorrespondence.org/

We're now nearly at the point where we have the letters parsed into
the db and in the web interface ...

Iain: I've now committed the updated cli/loader stuff so you can now
load letters (main.py) by doing:

$ paster load dickens
# or if you want to specify an ini file other than development.ini
$ paster load --config test.ini dickens

I plan to do some more work later on putting in some templates and
using them from controllers (e.g. for displaying letters).
