bug fix/improvement of select object (http://sourceforge.net/tracker/?func=detail&aid=3605240&group_id=55736&atid=478072)

reverted Miller's proposed patch as it suggests sluggish gui regression based on last 2 L2Ork rehearsals

added Jonathan Wilkes' canvasinfo and pdinfo externals (see http://osdir.com/ml/multimedia.puredata.devel/2007-10/msg00136.html)

fixed stray bug with utf8 support and symbolatom (thanks to Roman for a report). See http://sourceforge.net/tracker/?func=detail&atid=478072&aid=3160982&group_id=55736 for additional info.

fixed old bug that I somehow missed (thanks to Roman for the report). See http://sourceforge.net/tracker/index.php?func=detail&aid=1936157&group_id=55736&atid=478072 for more info...

fixed problem where using find/finderror would open the new window (where offending object is located) but would not properly select the said object

rewrote set component of preset_node to allow for empty [set< message, adjusted and expanded documentation

reworked how default hub and node now are given context via null global symbol s_ to make things more streamlined.

added "set" option to the preset_node to allow dynamic switching between hubs. added ability to have argument-less hubs and nodes that automatically default to "default." minor clean-ups...

fixed a sneaky bug where in specific cases preset was assigned to the wrong node, resulting in potential crashes
