Document release process

[mde]

There is a Jake task for performing a release jake publish (using a Jake builtin) that automatically bumps the version number, etc. This should be documented somewhere so people don't make manual changes to the version in package.json file, etc.

RELEASE.md? How about minor version bump? Does that have to be done manually?

[mde]

Bugfixes bumps are automatic as a part of publishing to NPM. Minor versions are manual.

But basically the idea being that anything with an actual number associated with it should be a published version.
