✍️ Description

Please see everything inside the dev-scripts folder!
I have a readme file with the breakdown and steps needed for the scripts.
Essentially what these scripts do is to setup a branch for creating a new helper script and automate a couple of things that may be forgotten like changing the build.func, install.func etc to point to the new branch instead of the official repo!
@michelroegl-brunner there you go mate, they're rough around the edge since they were developed for personal use but the workflow works! Although change_lxc.sh and cleanup_lxc.sh need a bit of more testing, new_lxc.sh seems to work for my needs pretty good (tested with 3-4 new helper scripts that I created a PR for them!)
