change version number of plugin to match ES version number
fix readme, change version number to match ES version number (why be confusing)
cleaning up errors in README.rst
update to ElasticSearch 1.0.0.RC1 and since our test framework is broken by this release of ES and that test framework is mostly replaced by ES test classes, I removed it and dropped back to the ES test JAR.  The tests are fragile in this system, and I think need some reworking.  One python test is disabled (index into another cluster), but the functionality is valid and it should be cleaned up and fixed when the tests get some smoothing out.
Merge branch 'master' into 1.0.0.RC1
