Renamed "indexName" to "index" and "indexType" to "type" for publicly visible methods, to have a consistent API.
Splat AbstractMultiIndexBuilder to two classes for multi-index and multi-type operations as the former does not imply the latter (but the previous version assumed this implication).
Fixed a bug in AbstractAction that caused duplicated parameters in produced URI when buildURI method is called multiple times.
Implemented Flush action with integration tests (tests for refresh parameter is missing, see the test class).
