- changed interface of NsfDStringEval to control behavior via bitflags (this is after all more readable than a argument list of "0" and "1"s) - added optional recursion prevention for functions called via NsfDStringEval (handling NSF_EVAL_DEBUG, NSF_EVAL_LOG, NSF_EVAL_DEPRECATED) - added regression tests for potential recursive calls
- replace all remaning ObjectName and ClassName with variant with trailing "_" when appropriate - allow nsf::procs with zero arguments or plain arguments (when "-debug" is used - extended regression test - bump version number to 2.1
