Minor build system updates

- Automatically set copyright date in Version class to current year
- parameterize source and target for javac, but leave at 1.6.  Setting source to
1.8 prompts the compiler to error "source release 1.8 requires target release 1.8"
- java compile target now uses deprecation and debug values set in -init target
- removed optimization argument.  Compiler ignores it
