A more idiomatic rb_main for MacRuby applications

rb_main.rb

# Loading the Cocoa framework. If you need to load more frameworks, you can do that here too.
framework 'Cocoa'

# Loading all the Ruby project files.
[__FILE__].concat(Dir[File.join(NSBundle.mainBundle.resourcePath.fileSystemRepresentation, '*.{rb,rbo}')])
  .map  { |path| File.basename(path, File.extname(path)) }.uniq[1..-1]
  .each { |name| require(name) }

# Starting the Cocoa main loop.
NSApplicationMain(0, nil)

Do check all the versions and the commit logs for the whys and wherefores;

kch$ git log --oneline --reverse -3
25197a5 step 1: get rid of the silly nesting and conditionals
f873413 step 2: require won't reload a file that's already been required, so
                there's no need to remove self from the require list
0e5d27d step 3: at this point we might as well do away with the variables since
                we don't need to refer back to any of them. FP FTW.

It seems I was silly in step 2, so, new commit:

While "require won't reload a file that's already been required", rb_main is never required, it's the main file, hence not in $", so I'm cleverly ditching rb_main from the require list again
