- library/nx/nx.tcl: Added the default procs for the init, defaultmethod, and unknown hooks to the ignore list for the ::nx::Object standard method set. Otherwise, upon a resourcing of nx.tcl (e.g., package forget nx;package req nx), they get registered as alias methods no matter what (due to residing in ::nsf::methods::object::*).
- nx.tcl: added support for positional object parameter and removed special handling of the last argument for the init block; added attributes "position" and "positional" to ObjectParameterSlots, removed last argument of method "objectparameter" - nx.tcl: simplified createBootstrapAttributeSlots (second round of default value setting seems not necessary) - nx.tcl: some cleanup
