Fixed auto-startup

Logic was switched. Tested and works.
Binaries obsolete.

Removed old ones. Added new ones.
Enabled dual build.

Now builds jar both with GUI and without. Also cleaned up some in the
code/files.
Renamed classes.

Also some cosmetic changes to the code layout.
Proper argument check.

Also prints out the correct command as help now.
Added mDNSResponder jar.

Isn't normally included in Linux. Helps with installation. Still
requires two native libs though (libjdns_sd.so and libdns_sd). They're
unfortunately platform dependant.
Updated README.

Bumped up version and added short description.
Fixed .gitignore

Flushed and re-added.
