As a user I want to use the following expression in configuration files:

If my static void main String[] arguments are:
--file foo.txt --verbose -x bar

I should be able to say:

- ${main:0} -> --file
- ${main:1} -> foo.txt
- ${main:2} -> --verbose
- ${main:3} -> -x
- ${main:4} -> bar
- ${main:--file} -> foo.txt
- ${main:-x} -> bar
- ${main:bar} -> null

For this to work, I have to call:
{code:java}
public static void main(String args[]) {
  //...
  MapLookup.setMainArguments(args);
  //...
}
{code}
