Disabling the stack trace and reversing the coffee|js search pattern

I added a --noStack variable to the command line.  It will not print out the stack trace if included.  I pass the appropriate variable via the config and options objects to follow the current implementation.

I had the array and search patterns reverse when coffee files are included.  I think this should make jasmine-node find the coffee version of a file first, and skip the compiled js version.  I have no way to test that at the moment.  Although, I am open to suggestions on how to.

Also, one minor change to use path.join in the filename variable to make the file search platform independent.

The code passed all unit tests in the specs.sh file.
