Merge in Pull Request #20 from Steeve Lennmark.

Adds support for repacking only the tables in a specified schema. This
doesn't support --only-indexes mode, but that seems alright for now.

Fix merge conflicts, and make a few tweaks along the way:
 * bump version to 1.3-dev0
 * add Beena to list of maintainers
 * documentation wordsmithing
 * fix up the INFO message printed for each index in --index or
   --only-indexes mode, so that it is only printed once per index, and
   prints the name of the original index, not that of the transient
   index_%u name.
