Start unifying options and the command-line: booleans

This commit:

- Adds a help field to options
- Adds a function to generate parser definitions from options
- Uses this to migrate all boolean flags over to the new system
- Makes all booleans consistently follow the --foo/--not-foo convention

There are a number of things left to be done here:

- Argparse doesn't give us a nice way to format --foo --not-foo help. Click
does, and moving to click is a goal down the track.
- For now, we remove all short aliases. I want to re-evaluate these
systematically once we have the new structure in place.
