Converts bindata usage to embed usage, gzip all http responses.

[davidnewhall]

• Removes bindata binary usage in favor of embed.
• Using embed alone caused the binary to grow by 7+MB.
• So I found a way to pre-compress all of the embedded files.
• Javascript libraries are re-committed compressed using zopfli.
• The GitHub and Docker builds pre-compress custom templates, js and css files before the build.
• The internal code now handles all of these assets with or without compression (.gz extension).

Bonus:

• The js and css assets are now served to http clients gzipped.
• I also added a library to compress all the html and api responses.
• The binary was 300kb smaller. Then I added brotli support and it went up by a megabyte. whomp whomp.
