Generation of graphviz (class diagrams, state diagrams, etc) will now put output where the --path option on the command line tells it to (this fixes an inconsistency, since other generators do respect --path)

Also, generation of graphviz now also respects the -c - option, meaning that svg files can be created directly from the command line if graphviz is installed. If combined with the -u option, this means that a single command can now create an svg of a diagram directly without even creating an umple file first.
