JFileIo 0.1.0

Added

• Initial versioning, includes process execution utilities (twg2.io.exec), simple logging (twg2.io.log), general I/O utilities, file filters, a rolling file renamer, and some other miscellaneous utilities (twg.io.files).
• Removed unused dependency on JSimpleTypes
• Removed test-check-util dependency in favor of eclipse project library reference, since it is not required at runtime unless calling methods from twg2.io.test.
