Python's keyword argument syntax is supported

[GoogleCodeExporter]

Python has so called keyword argument syntax which allows defining functions 
like

    def func(**kwargs):
        pass

and then calling them like

    func(foo=1, bar='two')

In this example the value of `kwargs` inside `func` would be a dictionary 
{'foo': 1, 'bar': 'two'}.

Supporting this syntax with Python based test libraries would sometimes be 
handy. For example, this would make it easier to add optional configuration 
parameters to keywords in the new Process library (issue 485). We would like to 
create keyword like this

    def run_process(command, *args, **conf):
        # ...

and call it like

    Run Process    ls    -h    cwd=/tmp

The idea would be that `conf` in the above example would contain {'cwd': 
'/tmp'}.

Most likely this could be implemented so that if a function implementing a 
keyword has keyword arguments, all arguments at the end of the keyword call in 
format `name=value` would be put into it.

If there are also default values, populating them has preferences:

    def example(foo='bar', **kwargs):
        pass

    Example    foo=zap    kw=arg    second=kw_arg

In the above example `foo` would get value `zap` and `kwargs` would be {'kw': 
'arg', 'second': 'kw_arg'}.
