#4 Make action-handling less strict

[TMBehrens]

the action handling of EnvironmentInterfaceStandard is far too strict. It
should definitely not be prescribed that an action is always mapped to
a method invocation of a constructed method name.
(you should split responsibility of performing the action which could be done
in any way and thereafter notification of listers)
