disabled drawing of tooltip arrows and improved positioning of floating tooltips due to unreliable nature of tcl.

This reverts commit f0435389.

merged patches from https://sourceforge.net/tracker/?func=detail&atid=478072&aid=2947822&group_id=55736

reenabled audio on/off in k12 mode now that the output.pd has a way of detecting preexisting dsp state.

added autopatch exception when patching new objects to circumvent checking of signal-to-non-signal connections since new empty objects are created by default with control (non-signal) nlets.

added verbose error reporting (based on Iohannes Zmoelnig's patch) on console from tcl side in case something is missing on startup (e.g. tkpng package).

implemented new tidy option that offers intelligent alignment when pressed once, and then intelligent spacing if pressed the second time on the same selection

removed hack for adjusting offset for select iemgui objects that introduce inconsistent drawing (those objects have now been fixed)

fixed hacky offset in the original object that made it draw with a unique offset, rendering autopatching and tidy implementation cumbersome without ugly hacks. will break backwards appearance (it will appear with a few pixels offset)
