Clean up cruft in distil_some_stuff.py
Giant cleanup and OO-ification of all the distillers
Update docs to reflect subclassing now
WIP: push distillers to provide more knowledge about themselves for introspection
Durr how did I miss doc_type on rt_ticket??
Well that ain't gonna work, get_distiller() is in localconfig now
Duhhh lern2classmethod, Barney
Fix indexing_worker the same as distil_some_stuff, so it actually runs
Add JSON request headers to the base Distiller class, it'll be commonly useful
update rt_ticket to use the class' json_headers attribute
Add Hobbsee's customer doctype
Clean up docs regarding how to add new doctypes
Specify a special output format for customer records, to make them all nice and pretty
Add the NewtypeDistiller, a fully functional example that can be used as a basis for new doctypes
Merge branch 'barney/objectify-the-distillers'

This is a huge set of changes that converts all the distillers into
something object-oriented and generally cleans up a lot of code. This
makes distillers much more self-contained, and should make it easier for
people to write their own distiller modules.

Particularly noteworthy is the addition of a fully functional demo
distiller that can be used as a base for new distillers. The docs have
been updated correspondingly (or at least all the ones I noticed that
needed fixing).
