Allow configuring the indent and newlines from config file.

When newlines are automatically inserted by this tool, the browser inserts spaces between inline block elements. This can negatively impact layout. For example see:

I propose to add configuration options for indentation and newlines into the config file defaulting to the current values of 4 spaces and true respectively.

I have problems with this as well, since elm doesn't put spaces when rendering elements, the prerendered layout and the hydrated one ends up different

As a workaround, I'm using this:

<%
  var html = require('../build/static/pages/index.html');
  var trimmedHtml = html.replace(/[\s\t\n]*</g, '<').replace(/>[\s\t\n]*/g, '>')
%>
<div id="app"><%= trimmedHtml %></div>

FWIW opening an issue in elm-static-html-lib. I really recommend switching to that if possible, since I plan to maintain that one going forwards, even after 0.19
