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

fixed bug where garray did not redraw its names when an array name has been changed via "rename" command

Overhauled preset_node and preset_hub to support any kind of data, including symbols, floats, and lists. Removed unnecessary global class declarations and object filtering for node and hub.

refined detection of illegal connections following autoconnect with an interactively-created (empty) object that is later turned into something else. Same goes for objects that have been fundamentally changed and recreated (e.g. where a non-signal [* ] object becomes [*~ ] and thus becomes impossible to maintain connection with a non-signal object below it).
