Manually inject a JS lib into a web page with load status feedback, either via devtools or a bookmarklet. Handy use case: facilitate devtools-based ad hoc scrapes with jQuery.
// N: lib name (eg, 'jQuery', 'Lodash')
// P: lib window property (eg, 'jQuery', '_')
// U: lib URL (eg, '//code.jquery.com/jquery-3.1.0.min.js', '//cdn.jsdelivr.net/lodash/4.15.0/lodash.min.js')
// for bookmarklet, prepend with "javascript:"
