Windows support

Habu now works on Windows! Note that I'm not a daily Windows user myself, so I'm happy to hear about any bugs or weird behavior Windows users come across.

Add stopped modifier to chains.

Stopping a chain is useful when you are no longer interested in tracking it but you want to keep the history and stats around.
Use modify <index> stopped <date> to stop a chain, or modify <index> stopped false to make a stopped chain active.
Stopped chains are not displayed by default, and their stats only include the dates from the creation date up to the stopped date.
Also add a new --show parameter to choose which chains to display.

Minor features

• Add habu version command.

Bugfixes

• Compute stats for the entire chain in info command, not just the last 30 days.
• Fix args check for habu help <command>, it takes 1 optional arg, not 0.
