riak-0.2

Eventer:
  - add partition to riak_vnode get/put/delete eventer notifications
  - export client-side send_event(EventName, EventDetail) for custom events
  - add Bucket, Key to riak_delete:delete_start event

Documentation:
  - most pages validate cleanly now (except for edoc)
  - more detail on the HTTP interface

Performance:
  - removed an unused async put operation
  - removed mnesia, locking, and spawn in riak_vnode
  - set garbage collection fullsweep_after to 20, globally

HTTP Interface:
  - new PHP client
  - allow dynamic creation of buckets (and schema) via HTTP/JSON
  - fix for sibling merge with dynamic json buckets
  - useful default behavior for linkwalking JSON data

Administration:
  - note in setup instructions that R13 or later is needed
  - added debug-restart.sh for interactive shell mode
  - explicitly put demo node on 127.0.0.1
  - allow_mult default value is now false; now "last write wins" by default
