Simple argument parsing for Props protocol

Browse source 
Maps foo=bar arguments to the top-level arguments dictionary of the
command, as strings only. (We could add CMake style foo:type=bar in
the future if needed). Very basic but this enables a bunch of useful
cases, since SGPropertyNode will do value conversion from string on 
access.
