add feature to "normalize" svg path data and pass it along as a FUDI message (e.g., "M0-2l3 4" becomes "M 0 -2 l 3 4")
This gets triggered when the user include the "d=" and double quotes as the object args to [draw path].  So [draw path d="M0-2l3 4"] triggers a conversion to [draw path M 0 -2 l 3 4], whereas [draw path M0-2l3 4] does not. This is necessary because Pd lets the user include scalar fields inside path data, and we can't normalize that.

Add a check that a toc entry actually exists before adding it. Added DISIS and Gem entries back to the toc.

handle negative coordinates for pd META regex, add doc/* directory search trigger, various refactoring

change id to the document's full path-- this will make it easier to fetch specific documents from the index when displaying directory contents
