kftgt 1.12

For kftgt, I could just use the macro that I developed elsewhere. So now I do, and it uses krb5-config like everything else. I also fixed a problem with make install when building in a different directory than the source directory.

You can get the latest version from the kftgt distribution page.

Hopefully this is the last release of kftgt that I'll do for a very long time, if ever, since soon we'll be eliminating the need for it.
