Pass IJS_Runtime, not IJS_Context, to native object constructors.

This better separates the two IJS_ classes, with the IJS_Context
taking on its proper role of describing an event. There's no need
for the event details for object creation, so this gets much
cleaner.

Move some JS error reporting code from CJS_Context to CJS_Runtime.
Make InitInstance() and ExitInstance() voids, they always return
TRUE and we never check the result anyways.
