Finalization of speech detect interface and API

Browse Source 
This changes the core to have the necessary tools to create
a speech detection interface.

It also changes the code in javascript (mod_spidermonkey)
there are a few api changes in how it handles callbacks

It also adds grammars as a system dir to store asr grammars
