Move schema file(s) to more appropriate path
URL encode api scopes

When I tried to add drive.metadata.readonly scope to FusionIndex's
scopes, the getAuthUrl() method threw invalid url exceptions, owing to
invalid characters in the URL; encoding the scopes before building the
url fixes that.
Table list and permission view

Added action on IndexTool to show a user's tables and the perimissions
on them.
Added drive.metadata.readonly scope to apis on FusionTable to support
the permission view
Added a work around for popping up the default browser to grant
permissions, as I don't use the default browser for Aikuma-related
stuff.
Documentation changes
Schema update and tool support

Added ability to add columns to table via tool
Update schema to include new info column (per LP-42)
Added example .aikuma file

The IndexTool uses a dot file in the home directory for info like
access_tokens and the ID of the aikuma_metadata table. Including a
sample so a user can recreate it for their own use.
