We no longer add observable annotations to the constructor.
Instead, we just mark getters (and for read/write properties
also setters) with an observable annotation.
This is a temporary measure until Plovr handles custom tags or is replaced in the build system.
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)
