Enhancement: Run scripts using a working directory of the script path

[klauer]

Suggestion

• For external scripts, ensure that the working directory is set to the script path
• For example, if a script is in /tmp/scriptname.sh, LUCID should run it with a working directory of /tmp.
• This would avoid users having to manually do a cd /absolute/path or a cd $(BASH_SOURCE...)-style incantation

Background

I haven't dug into the code just yet, so perhaps something else is wrong here. Anecdotally, I've had a couple people fix their LUCID commands by just cd'ing to the appropriate path as a first step in their script
