Details! - Skin 'The War Within' (Dark)

Fork of https://www.curseforge.com/wow/addons/details-skin-the-war-within

Originally opened a pull request to add dark mode version of the above mentioned skin for Details, but author seems to be unresponsive its been over a month.

More and more people have been asking for this and it's not viable to have everyone downloading a fork from github to install to addons, so I am just making it standalone, hopefully in future can deprecate this and merge with original addon as separate skin selection.

Anyways.. This addon just adds a dark mode war within style theme for Details!
