merge go1.16 changes
This includes embedded files for releases (no extra 'data' directory!)
and support for a custom language file directory, allowing one to
customize the text accross the app.
significantly faster builds now. Every pre-compilation step (typescript,
css, etc.) happens natively, then GOARCH=xxx make compile is also run
natively for each architecture. The output it then copied into each
container.
the web ui has been redesigned with the a17t toolkit, which imo looks a
lot better than bootstrap. This also brought a complete rework of the
web code, which now makes a lot more sense hopefully. the setup page is
still stuck with bootstrap, its not much of a priority but i'll rewrite
it eventually.
