I can push tags to gerrit to release wikipeg through composer, but only @tstarling can currently release npm packages (see https://www.npmjs.com/package/wikipeg/access while logged in to add new package maintainers).

In addition, some version numbers in the source need to be updated before it is released; see I8fbb65d52d23ef1c63764845d8061dbbeedcf83c.

(Note that I prematurely pushed a 2.0.2 tag to composer to unblock parsoid, but I botched it by neglecting to update the package.json version number. So we need to push both composer and npm to 2.0.3 to skip over my 2.0.2. Sorry. :( )
