First version of pepper api implementation:

Adds a severely pared down version of webplugin_delegate files
that are not currently used to create any instances.
Also adds calls for render APIs that remain to be
connected to the impelementation.  The function pointers are
returned by NPN_GetValue calls with new enumerated values.
I have also added Nicholas' NPEvent definitions.
These changes are to permit further collaboration between
sehr, brettw, and cpu.
