Create a parameter parser

Create a class `Joomla\Application\Cli\Parameter` to make easy work
with parameter by command line. After, we can't get paramerters passed
to our cli application by `Joomla-framework` interface. Now, if we want
this, have to instantiate a Cli\Parameter an use that.

Example:

    use Joomla\Application\Cli;

    $inputFromUser = '--force=change -v';
    $parameters = new Cli\Parameter($inputFromUser);

    var_dump($parameters->has('--force')); // true
    var_dump($parameters->has('-n')); // false
    var_dump($parameters->getParameter('--force')); // change
    var_dump($parameters->getParameter('-v')); // 1
    var_dump($parameters->getParameter('--super-force')); // false

A more easy way of work with parameters.
