Postponed HUD 2.0 features

This blueprint is a PROPOSAL and it outlines the work items for completing the HUD 2.0 if it gets postponed according to https://blueprints.launchpad.net/hud/+spec/hud-20-converged-service

When these items are completed HUD 2.0 will have:
* Fully documented and tested public C and Qt/qml API for application developers
* Support for parameterized actions
* Support for actions exported by background applications
* Voice recognition
* Toolbar support including default actions (quit, copy, paste, etc)
* Providing a list of applications supporting a queried action
* Support for action alias names to make actions more intuitive
