nsfDebug.c

- nx: added flag "-debug" and "-deprecated" to methods "method" "object method" "alias" "object alias" "forward" "object forward" such one can use e.g. /cls/ public alias -deprecated|-debug /method/ ... /cls/ public forward -deprecated|-debug /method/ ... /cls/ public method -deprecated|-debug /method/ ... /obj/ public object alias -deprecated|-debug /method/ ... /obj/ public object forward -deprecated|-debug /method/ ... /obj/ public object method -deprecated|-debug /method/ ...
- added new cmd:
nsf::method::property /obj/ ?-per-object? /method/ exists
to check, whether a method is defined for an object.

- output triggered via "-debug" is now generated via the
tcl functions "nsf::debug::call" and "nsf::debug::exit",
that can be redefined (similar to e.g. nsf::deprecated)

- cleanup of nsfProfile.c commands

- extended regression test
