Publish a new version of @yaakapp/api

The npm package @yaakapp/api contains the type definitions used for authoring plugins. The latest version currently available in npm is 0.7.0, which is 3 months old. Since then, new additions have been made to the package, such as PR #340.

However, for these additions to be available to plugin developers a new version of the package needs to be published to npm. In the source code the version definition is 0.7.1, which indicates that a new version was developed, but was not deployed to npm.

So, this is a request for the latest modifications to the @yaakapp/api npm package to be published.
