Fixed the bitwise flag comparison in ProtectionMatches() which failed to yield a boolean result. This resulted in unanticipated [obj info methods -callprotection] behaviour, with the -callprotection filter seemingly being ignored. Added some tests to tests/info-method.tcl.
- made methods (for now just scripted methods) by default protected. - provide methode __default_method_protection to obtain the default method protection when neither protected or public is used. - per default methods are now protected - provide ::nx::configure defaultMethodProtection true|false as conveniant interface - update regression test and serializer to handle default protection
