* ACS-953 Unable to upgrade from ACS-7.0-M1 or ACS-7.0-M2 to ACS-7.0-A12
Now that we create internal releases of the form M.m.r-M9 (milestone), M.m.r-A9 (alpha) and M.m.r-RC9 (release candidate) during development and testing, we need to ensure we can upgrade from any of these to any other, as they may occur in any order and also to the final external release M.m.r. We also will allow a change from the final release back to an internal one for regression testing. The code within ModuleComponentHelper which calls this method, checks if it is the same version (0) and then if it is downgrading (> 0), so if they share the same M.m.r part matches AND is one of these formats, we return <0.
This PR removes legacy Lucene code and dependency to the lucene 2.4.1 library.
The data type analysers were removed with an exception of the definitions in models (datadictionaryModel.xml and cmisModel.xml) to be backwards compatible with existing components (like older versions of Search Services) and to ensure the current old-style models can still work with repository and pass validation.
