removed long term usage of putting dot into the PATH, to allow scripts and exes to be run
if they were present in current directory.  have long known this wasn't totally safe, but
the reason for even doing it has long passed.  all of feisty meow aliases and functions and
scripts are loaded up so that one can run them without needing to refer to a file in the
current directory, and for anything that's actually right there in the current directory,
i will just add a "./" in front of it from now on before running it.
