Add a general-purpose parse_list function to parse a string containing a delimited list of items and adapt the parse_image_load() function in the WPS parser to use it.  This function will also be used to parse the upcoming WPS %V viewport tag, but I'm committing it separately as these changes are unrelated to the viewport implementation itself.
