- activated SKIP_LAMBDA in nsfCallstack. As a consequence, we disallow resolving self/my ... from tcl-proc frames (use uplevel if necessary, avoid "namespace eval")
- added new contains definition based on "apply" instead of "namespace eval". Main intention is to replace SKIP_LEVELS by SKIP_LAMBDA - added functionality to use ":attribute contains:method,nosetter" - added regression test for contains and attributes of type method
