Add logic for parsing commandline options, and a preliminary stub for
loading modules.
Note: The idea is that core.module.load() will return a valid, but
empty, module that displays an error, if the module cannot be loaded
Experimental re-implementation of core functionality with the aim:
- Depend only on the Python Standard Library for core
- If modules are missing elsewhere, *never* throw
- Unit test *everything*
- Cleaner and more minimal implementation
- Better integration points for existing implementations (charts,
braille, etc.)
- Full backwards-compatibility with existing module system (except where
modules can be vastly simplified)
If an import fails, this test fails, which is not the original
intention.
Until such time that the listing of existing modules is fixed, this test
is removed.

Seems like subprocess and friends (Popen, communicate) are not so easy
to mock cleanly. Therefore, start from scratch and carefully write test
by test, until (at least) the old test coverage has been restored.
Allow the user to provide aliases when loading a module multiple times
so that the modules can be differentiated (e.g. for passing parameters
to a module).

This is going to be a bit more comprehensive than anticipated. In order
to cleanly refactor the core and the engine, basically start from
scratch with the implementation.
Goals:
* Test coverage
* Maintain backwards compatibility with module interface as much as
possible (but still make modules easier to code)
* Simplicity
see #23
