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)
Replace textwrap.shorten() with custom implementation, since it is only
available since Python 3.4. While at it, catch i3 exceptions in order to
make unit tests (hopefully) run through.
Also, Updated README.md
see #174
