Allow setting a mapping on a URL directly on a request

[mitchhentges]

After clicking on a request, there should be an option to set a URL Mapping for it in the details view. Alternately, with some magic, rearrange each row so that there's a button on each that allows each mapping-setting (would appear on-hover)

This is the same as Add Mapping from the request context menu, right? Just adding a button somewhere on inspect-request, if I understand correctly.

Kind of wondering if we should just add an overflow menu on inspect-request and reuse request-context-menu.

Oh wow, there is a context menu. :O Yeah, a button would be pretty sweet for this.
