Add an option to prefer "--" arguments over "normal" arguments

[boenrobot]

When making command line applications, you sometimes want to make sure you separate the PHP options from the application options. Plus, some options are simply handled by PHP already, thus making their use impossible (e.g. "-d", "-l", etc.).

However, Console_CommmandLine intentionally ignores everything after "--".

There should be an option that allows users to prefer the collection formed from arguments after "--" (i.e. WITHOUT any options from PHP), assuming "--" is anywhere in $argv, and fallback to the current behavior when it's not.
