Using bulk API for migrating data between indices, should make it faster
Merge pull request #38 from MichaelDrogalis/master

Adds support for Hive.
Added hive to joplin.lein and cleanup of the README. Also having all
plugin dependencies in joplin's main project.clj is no longer viable.
update-index now updates an index's settings/mappings in place, while clone-index takes over
old behaviour of update-index.
