update unit tests, extend MESSAGE-scheme flexibility_factor indices (…

…#7)

- refactors the unit tests and test-database to separate MESSAGEix-GAMS-specific tests from general tests and MESSAGE-Java-specific features. The Austria tutorial will be migrated to the the message_ix repository.

 - includes a new ixmp.jar file, fixing a bug with the Platform.getUnitList() function.

 -  switches from Java.ext.dirs to adding the library jar files to the classpath explicitly    using ext.dir may cause problems when multiple Python packages use jpype.

 - changes the index sets of the MESSAGE-scheme flexibility_factor parameter, and renames an index set to rating bin for a more comprehensive implementation of the Sullivan renewables formulation.
