1.7.4 Save Copies of Stylesheets and CSS minification

To save some crucial load time and bandwidth for mobile users, it is custom
to compress stylesheets and scripts (the process is usually called
minification). Considering this, it would be highly beneficial if the saved
stylesheet were saved in a pretty-print manner to facilitate authoring by
users.

Note that minification is not as important for local stylesheet as files
loaded locally don't incur the overheads of HTTP requests.
