Remove haml ugly:true and add minify_html for blog-only (blog post) middleman config
What does this MR do?
Remove haml ugly:true and add minify_html for blog-only middleman config
minify_html omission causes differences in rendering from normal builds (quotes are added), which results in unnecessary file diffs vs master and slower uploads during review app deploy.
It's unclear why ugly:true was added, it appears to be no longer valid: https://github.com/middleman/middleman/issues/2087#issuecomment-307502952
