Update of quite old setup

[SergeoLacruz]

Hi,
I just found an Inventree 0.15.something bare metal installation on an old ubuntu server that had not been used for more than a year. Give it a try:

git pull
install the tools for new UI like npm, tsx, ...
invoke update

The only thing I needed to change was the config.yaml because it was moved to a different location. All the rest worked
out of the box including the new UI (We will come to this later) and database migration on more than 2000 items.
Congratulations to the dev team. This seems to be quite robust even when you skip several revisions.

Django is quite robust and we test migrations so it should work pretty much for the last 5+ years. The moved config file is interesting, we had included fallback but they seem to not work
