Do not prevent calling declareGadget in ready functions.
Allow to directly declareGadget inside the HTML.

Only ease to ease developper comprehension.

Drop EventTarget support on Gadget.
Add declareAcquiredMethod, allowPublicAcquisition.
Prefix attribute non part of the API by __. Such method/property can be rename
in next versions without any compatibility support.
Use base element in iframe to get the same link behaviour with or without
iframe.

declareAcquiredMethod generated function should not call local (ie, same
gadget) allowedAcquisition method.

Use declareAcquiredMethod instead.

aq_dynamic was a "low level" method, somehow hard to understand.
Allow acquisition more explicitely by providing the method name allowed.

Replace the gadget method "acquire" by the Klass function
"declareAcquiredMethod" which generates new accessors on this class and do a
direct mapping with the parent aq_dynamic function.

Acquisition will be the only way to propagate informations to the parent
gadget.

It may help developper to see all properties which are not part of the API.

Add methods to fetch an existing gadget from its scope and drop the scope
reference.

Thanks to Thibaut Frain for this patch.

Display the error in the console.

The method .on, .off, .trigger have been added.
See RSVP.EventTarget.mixin for full details.

Propagate the events in case of EmbeddedGadget to the parent IframeGadget.
