- nx.tcl: added default/initcmd for ObjectParameterSlot - added ::nx::Object as default for "superclass" slot to make default superclass explicit - unified interface for getParameterOptions - extended regression test
- nx.tcl: * full rewrite of slot machinerie, much simpler structure * relation handling via parameter aliases instread of pseudo converter * mixinclass SlotOptimizer removed * new class BootStrapAttributeSlot - ConvertToRelation() and handling of parametertype "relation" - Make CompiledColonVarFetch() more robust in case of half initialized objects (create vartable on the fly if needed) - allow empty parameter options in parameter parser - removed nsf::parametersfromslots (became simple, part of objectparameter now) - removed hardcoded objectparameter (attributes, volatile and noinit) - updated regression test
