Subject: [PATCH] Use Alpine base image (#205)

wgquick (apparently) depends on bash and openresolv.

Without those packages removing an Interface is impossible and causes an error message to appear in the webui:
- No Bash: exec complains about "bash no such file in $PATH"
- No openresolv: resolvconf -f -d *interface* returns with error 127

Not having a Shell in the container also makes debugging a lot more annoying.

This enables deletion of interfaces in the webui, eases debugging and only adds about 3MB in size.
