- Revert version to 2.1.0-SNAPSHOT
- Fix "Apache License" name in pom.xml files (was "The Apache Software License")
- Fix Apache copyright year range in NOTICE files
- Some formatting in README
- Added missing sections to NOTICE file for binary distribution, conflating redundant parts for UIMA artifacts and uimaFIT artifacts
- Removed redundant sections from NOTICE files in individual modules. These files contain only module-specific *extra* sections which are added to the auto-generated Apache UIMA uimaFIT section.
- Changed module names from "uimaFIT - XXX" to "Apache UIMA uimaFIT - XXX"
