fill-in gem licenses + update home page
md-ize and update README
avoid using JRuby IO APIs (will likely not work in 9k)
cleanup - do not catch too much (e.g. java.lang.Error !)
make these internals a little more readable
revert "dummy" class deletion - it's actually used within the internal API
make sure we only include commited pieces + the .jar files with the gem
