Title: Allow to specify which indices to index

Riddle already has the capability to index only certain indices.
Unfortunately, Thinking Sphinx does not make use of this, so
indexing always happens with `--all`.
This change adds the `INDICES` option to `ts:index`.
When INDICES is set, only the specified indices will get indexed.

Usage example: INDICES="user_core post_core" rake ts:index
