Release Name: 0.0.5

Notes:



Changes:
* Supports keeping lucene index in memory instead of on disk
* Added support for lucene full text search
* Fixed so neo4j runs on JRuby 1.1.5
* Implemented support for reindex all instances of a node class. This is needed if the lucene index is kept in memory or if the index is changed.
* Added ReferenceNode. All nodes now have a relationship from this reference node.
* Lots of refactoring
* Added the IMDB example. It shows how to create a neo database, lucene queries and node traversals.
