fixed regression in the iemgui move handle for object labels where text would erroneously disappear as a result of a commit earlier today

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

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

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.

Finished fixing inconsistency from the iemgui and non-gui fonts. This will break font appearance in older patches but looking forward will make things a lot more consistent. This is in part backported from the 0.43 branch.

fixed all iemgui objects to conform to the new model of gop selection (no highlighting of objects inside gop unless they are toplevel objects)

Added support for moving GOP objects via tag and disabled showing of resize handles on iemgui objects when displayed inside a gop window (this became an issue due to new way of selecting gop objects which now also includes all objects inside it).
