Bumblebee-status

fixing 658 (regression in `shell` module - thanks to es80)

The changes in this release are really too big to list, essentially, it's a rewrite of `bumblebee-status`, with a focus on greater extensibility and better code testing coverage. Also, the documentation is much nicer now, I hope :)

As such, I unfortunately cannot drag up a full list of changes (modules, themes, fixes) - apologies for everyone who goes unmentioned!

Also, this release probably contains numerous bugs and regressions - sorry for that as well!

Many thanks go out in particular to TheEdgeOfRage , martindoublem , bbernhard , somospocos , fredj for alpha-testing and valuable, early feedback!

This is the "rescue" release before merging the current "development" branch into master

Another PyPI packaging bugfix release.

For the life of me, I cannot figure out how to properly do a *manual* release cycle with versioneer and modified/unreleased versions.

Let this release branch (1.10.x) be a testament to my inability to handle packaging and releases, and a caution to everyone else :(

Another bugfix release to get the PyPI working
