Add support for indicating API stability with inline documentation
In preparation for documenting the stability of API features, this commit adds support for indicating API stability via a new jsdoc tag @stability. There is a small plugin for jsdoc that adds a new tag, @stabiility, with some ability to enforce specific level names. The templates and css have been updated to include the stability level in the generated documentation. (+1 squashed commit)

[d6bc03d] Add jsdoc plugin for documenting observable properties of a class.
This renames the doc task to apidoc. The apidoc delegates to jsdoc3 currently. We will have additional documentation that is not built by jsdoc3. It makes sense to reserve the more general 'doc' name for building all documentation (not just apidoc).
