Unable to pass --help argument to Ceylon tools

ceylon run foo.bar --help will print the ceylon run help, even though the option belongs to the module being run, not ceylon run. This means that a Ceylon program started via the command line can’t print its own --help message.

Probably related to #1228 (although --version works fine).

[@quintesse] I was sure there was already an issue for this but of course I can't find it now.
I'm aware of this problem and has to do with the fact that --help is the only option that's very much hard-coded into the tool framework, I was able to get rid of the other hard-coded things but this proved to be a stubborn option.

Btw, you can work around this problem by using -- between the Ceylon tool options and the options you want to pass to your program.
