- Managing the add/update of values in InstalledIndex.prop programatically
- location of prop file : WritableProjectDir}/JSword/lucene
- Added PerBook module Version in the property name
getInstalledIndexVersion() usages has been moved from IndexMetadata to InstalledIndex.
The InstalledIndex version still returns 1.2 , so should be back compatible
fix NPE if Version is not available
added usage sample method LuceneIndexManagerTest.createOrUpgradeIndex()
Refactoring for cleanup
