Can specify keyword arguments with a dictionary

You can now specify keyword arguments for any function and method call with the kwargs keyword argument. This is perhaps best described with an example.

options = {'include_directories': include_directories('inc')}

...

executable(...
  kwargs: options)

The above code is identical to this:

executable(...
  include_directories: include_directories('inc'))

That is, Mesn will expand the dictionary given to kwargs as if the entries in it had been given as keyword arguments directly.

Note that any individual argument can be specified either directly or with the `kwarg`` dict but not both. If a key is specified twice, it is a hard error.
