Improve profiling support - added profile support for undispatched methods (i.e. implemented via CallDirectly) - new function for controlling profile trace nsf:__profile_trace -enable /bool/ ?-verbose /bool/? C-code generator: - allow type boolean for non-positional arguments
- changed trace facility to append to a variable to minimize interactions for results and return codes, which happen via nsf::log. - added more convenient function for adding to DStrings: Nsf_DStringPrintf - renamed NsfDStringPrintf to NsfDStringVPrintf - replaced complex macros for tracing by functions
