Fixes:
- Changed the logic around regctl checks and downloads.
- Will check $PATH (as before) but additionally instead of using relative path of./regctl
it'll use the scripts working dir as a base.
- So regctl will be checked/downloaded alongside the scripts location. no matter if it's in~/usr/local/bin/dockcheck
or~/dockcheck/dockcheck.sh
or other.
Special thanks to @Impact123 who suggested the changes.
