Custom destination

[ostowe]

Updates:

• Change primary property from critical to critical-selector
• Add scope option for critical-selector to move a selector and all its children to critical CSS
• Add critical-dest property for arbitrary alternate destination files
• ouptputPath option for output directory
• preserve option for removing/saving rules flagged as critical
• minify option for minifying output with cssnano

Note/Question: The scope value has the effect of dragging in related, but unnecessary group selectors. For example, if you use critical-selector: scope on .news-item, it may drag in a selector like .container:after, .news-item:after, .third-selector:after, ... {...}. I considered pulling out only the relevant selector, but wasn't sure if that might have unintended consequences or simply be a Bad Idea™. Currently it brings in the entire selector; I felt like transforming the selector without warning is not a good plan.

The other option here is to only bring in selectors that begin with the parent: so no combo selectors.

Merging this! Better late than never, hopefully—this was a rad update. ⌛
