- Eliminate use of the C++ standard library from arttool. I improved some of the program's workings but it continues to corrupt my art files in certain circumstances. (Note: Not a regression; it happens with previous revisions.) - Construct "make utils" for the game side following the pattern of the engine. - Move ivfrate to this new distinction. - Minor Makefile cleanup and tweaks, mainly to facilitate CLANG=1 and to formalize text output in special cases. git-svn-id: https://svn.eduke32.com/eduke32@3163 1a8010ca-5511-0410-912e-c29ae57300e0
