Detailed Description

API for registering and calling event-listeners.

TODO:

• Only default onFoo() style listeners are supported, custom addEventListener() doesn't work yet.
• Many widget handlers are friend classes to the widgets to access internal data. Instead widgets should have APIs to manipulate their state anyway, which they don't have yet.
