DLL building for release

This adds a DLL building step for ./all release.

It also removes a few deprecated lines. I tried running it in a Debian machine and it works. It might need to add the ability to ssh to a separate machine if the host is not in $HOSTS_THAT_ARE_MYSELF. Any help is greatly appreciated.

It seems to work for me but it needs some work and feedback so I'm submitting it as Draft. Feel free to commit into my branch.

Fixes #323 (closed) and #337 (closed)
