To Run on Node 14

[bvandenbon]

Description
I just tried about an hour to install it on my server, (which already runs other node 14 applications).

I first tried to run it in a docker, which didn't work.
Then I decided to just clone the git repo and install it.
Then I went through a range of different issues:

Issues with bcrypt, issues with node-sass, issues with gulp versions
So, in the end, I had to give up.
