Bump to Caddy 1.0.0 about caddy

[pascalandy]

I took a look at https://github.com/swarmstack/caddy/blob/master/Dockerfile (which is a fork of your repo) and I had to update the www dir. Then it worked.

Then I decided to add upx.
Then I decided to put the final layer into alpine to have curl in the final image. Needed to do my health check.

If you like it, I can do a PR.

Cheers!

I switched the build process to rely on go.mod's resolution of packages and package versions, removing a lot of unnecessary scripting during the build process. I also added a short script to generate the main package from a comma-seperated list of packages, copying the functions of and removing the dependence on abisoft's caddyplug package.

@pascalandy Thanks for your suggestions, they helped!
