CPAPI gears drag drop and renderer IPC....

CPAPI (0.10) functions for gears drag drop; one to extract the
drag type/data given an NPObject *event, one to override the
drop effect (drag cursor).

Gears drag drop API receives a browser event as an NPObject* so
the event is untrusted.  Provide IPC calls to the renderer so
gears can pass the event to renderer/V8 for checking, prior to
drag type/data extraction, or the setting of the drop effect.

V8 event checking is a TODO(noel), http://mondrian/10947778 for
the CPAPI (0.10) change submitted to gears.
