Hugo Pipes added minification support for resources fetched via ´resources.Get` and similar.
This also adds support for minification of the final output for supported output formats: HTML, XML, SVG, CSS, JavaScript, JSON.
To enable, run Hugo with the `--minify` flag:
```bash
hugo --minify
```
This commit is also a major spring cleaning of the `transform` package to allow the new minification step fit into that processing chain.
Fixes#1251
If hugo server is run on port 80 or 443, LiveReload does not
correctly bind to the same port, instead using port 35729.
This commit adds functionality to inform LiveReload of the
correct port to bind to.
