Release 0.11.7

I've spent the past few weeks working on build systems for other
projects, and this has paid off in having a better understanding of
things here.

The NPM package should now be much easier to use now.

Major changes:

- TypeScript definitions (f47e38c)

- Support for importing teams (ddb6010)

- A CLI for exporting teams (ddb6010)

- `lib/` available as an unstable API in the NPM package (147b7e0)

- Lots of documentation updates (a813a55)

Release 0.11.6

semver? what's that? Seriously, though, the major breaking changes
are all in undocumented APIs.

Notable changes include:

- A new Dex API (smogon#8181)

- `lobby` is no longer special-cased (messages without a roomid now
  always get sent to console rather than lobby)

- A new challenge API (smogon#8303)

- A new system for specifying battle rules with numbers and other
  options (smogon#8267)

Release 0.11.5

This is mostly to get d4b6ba4 to npm.
