nsf.c: - allow parameter option "method=" for slotassign as well. rationale: this allows to use the parameter "forwardername" to specify a different forwarder target method (e.g. in case of object-mixins). The method is used both in "configure" and "cget". - allow methodname to consist of max tow words in relation slots (e.g. "-methodname {mixin set}"}
- add flag "-onerror" to nsf::forward::method to handle errors during dispatch of a forwarder (not all error messags of forwarder are already transformed) - added log-level Info which prints always, e.g. for "-verbose" flag of forwarder - drop setter-rule from properties (use always forwarder) - drop "/obj/ /prop/" and "/obj/ /prop/ /value/" in favor of "/obj/ /prop/ get" and "/obj/ /prop/ assign /value/" to achieve better orthogonality with e.g. incremental properties
