Cython interface compiles, but doesn't work

Trying to import the cython-generated interface module to python causes
the process to (unbreakably) hang indefinitely
Removes Cython interface

Cython was creating modules that hung indefinitely (and unbreakably) on
import; it was not working, and in general has somewhat poor C++
support, so I'm transitioning to boost::python
Implements boost::python wrapper

The boost::python wrapper for bots::user is written and compiles, but
causes the same infinte hanging on import as the Cython interface. I'll
try implementing the wrapper using the bare python API
Fixes hanging import

The static declaration of the user::bot_db and user::trade_db attributes
was causing the import hanging, as CPython has a global import lock,
which was causing the hanging

The build process is not totally worked out yet (make names the
extension incorrectly), but the code itself works, and runs;
I haven't checked functionality yet, but the wrapper class
initializes properly
Merge branch 'develop-cython' into develop

Conflicts:
	cryptobot/bots/Makefile
	cryptobot/bots/config.mk
	cryptobot/bots/interface.pyx
Fixes compile errors from merge

Some changes were made to develop when I was testing out SWIG and
boost::python, and the merge included some of those incorrect or just
outdated changes). The build is fixed, and so is the module
structure; I made the lib (output directory) a package, so you can
import the Cython interface to bots::user using something like
'from lib import interface' (after running make)
