Docker will use fuse-overlayfs in my lxc container.
The problem is that when the file is moved, the mv command returns with
error, saying it's the same file and cannot be moved. This is because
under the hood, the file is actually the same. Easiest fix is to cp it.
Add variables and rework the docker files to allow building with
different name (i.e. not 'openwebrx') and upload to different docker hub
account.
Rework the build system, to safe bandwidth (not installing dependencies
with every script) and CPU. On my system this made the building of the
full image in 35 minutes, instead of 60+ minutes. This will allow us to
have a -nightly builds, without spending much CPU and BW on the server,
which will compile them.
