Update instrumentation for generating metadata.

- Fixed index.html. Now, running it simply generates the JSONs (does not require checkout of SVN repo)
- Added these auto-generated JSONs to the bundle
- Updated the plists with the ones that were generated.

There is still a manual step involved in copying the generated plists from the simulator's container (since the file is saved by the app in its documents directory).

Note that this updates the metadata to r729 on the libphonenumber's svn trunk.
