Provide script/gypi support for manifest generation

This provides a gypi action including well-defined variables, a python script, and a first client in ChromeVox (main and guest).

This generation code was born out of necessity as ChromeVox evolves and requires a varying set of manifests depending on such factors as compression strategy, debug/release builds, Chrome webstore releases, and ChromeVox next (version).
