Title: The least number of changes to schema.xml required to get Solr 4 to start, fixes #301

Added fieldType int, float, long, and double. Added field _version_.
Both changes are taken from the example schema.xml shipped with Solr 4.

Note: Added the schema.xml as schema4.xml because I doubt it is
backwards compatible to Solr 3.x.
