added logic for --copyconfig for systems with only python3

[m4lwhere]

This change helps systems which only have python3 and not python to copy the initial config file. Without python2's python available on the system, the --copyconfig switch fails to create the working config for the initial run.

Hi @m4lwhere,

Thanks for the PR. I see there are a few other changes in the commit as well. Are those intended?

Hi @jayjb

Not directly in this commit, this was my first PR I've ever done. 😅

I was planning on submitting those later once I tested the MongoHandler a little more. Would you be interested in me submitting the Mongo Handler once I have the kinks ironed out?

[m4lwhere]

Reverted the changes in the second commit, I'll submit a new PR when those are ready

Thank you so much for the PR! We really appreciate it.
