Changes

[These changes in the enc/map file locations may give users who have their own font trees some headaches; also, if you use scripts in your own scripting tools e.g. in server apps, then you should be aware of the fact that locating scripts needs patches, i.e. the format fed to ''kpsewhich;'' Here I have so many scripts that I don't put them all in the path, for instance because of name clashes, and I used to use ''kpsewhich'' to locate them; using ''texmfstart'' in such cases is more future safe, and with the coming new kpse run-as-deamon libraries it may become faster as well.]
