fixed tooltip positioning on larger windows, fixed color inconsistency on nlets when used with tooltips

completed transition to the more optimized way of redrawing items on canvas following editing operations (e.g. cut/paste/undo/redo etc.). Implemented better version of the duplicate undo/redo action that also stores offset info

improved redrawing logic for undo cut/paste (need to check remaining undo/redo actions), other minor cosmetic fixes

fixed color inconsistencies in gop and array objects when selecting/deselecting, introduced optimized redrawing of gop objects

improved tooltip reliability in K12 mode, made preset_hub hidden in K12 mode in respect to tooltips, hopefully fixed dancing scrollbars with an ugly workaround

fixed nlets not being properly selected after gop object has been redrawn, improved redrawing speed with gop objects

improved redrawing of tooltip arrow logic to minimize visual artifacts during updating of arrow while maintaining mouse position within the same object

implemented universal catch{} for all commands sent from c to tcl to minimize (eradicate?) stderr output.

binbuf_print now hides all arguments following the %hidden% atom when reporting errors on the console

fixed show-stopping bug inside the preset engine, causing random crashes and failing to properly store preset_node locations

added ability to provide custom name to the pd-gui instance (for combining all windows under the same icon on recent WMs (like Ubuntu's Unity), made all toplevel windows inside pd.tk inherit the class name of the root window, added new ways to select and edit text inside an object (ctrl+left and ctrl+right take you to the next argument, ctrl+shift+left/right select the same space, shift+left/right alter selection, home/end or down/up take you to the end/beginning of the text entry).

fixed remaining bugs with asynchronous nature of various ways to enable edit mode/cord inspector/tooltips in K12 mode

added workaround for a proper redraw of duplicated objects that left stray nlets if they were gop abstractions
