Minor update to U-235 Disassembler

A new version of the Disassembler has been made available, there are only some minor improvements here.  The project that this was being developed for has been put on hold due to other commitments, however I have pushed this to release as it resolves a bug that was raised indicating an error with JRISC GPU pack/unpack instructions.  This build resolves that issue.

If you are using this disassembler against Jaguar RISC GPU code, I would recommend you update to the latest version.

Details of other changes are in the changelog.

(Want this for another platform other than Windows? if so, please let us know)
