- cleanup of legacy stuff in slot management. * merged InfoSlot and InterceptorSlot into RelationSlot * get rid of legacy "mixin set ...." command - renamed "parameterSlot" into "methodParameterSlot" to avoid potential confusions
- define everything concerning basic slot setup in a single "namespace eval ::xotcl {...}" - undefine ::xotcl::createBootstrapAttributeSlots after this block - fix default DefaultSuperClass() with isMeta==1 in cases, where we are already at the root meta class - use "-parameter" in xotcl1 instead of createBootstrapAttributeSlots
