Some issues might still exist, especially the issue of inline CSS used in too many places, but this one provides a pretty good option for now.
Notice: This patch is mainly a clone of application.css with RTL overrides, but it is better than before and there is more to come.

We originally worked on the 2.4.3 version of application/rtl.css, but I fitted it to meet the master branch version.

File: public/stylesheets/rtl.css
Branch: master

He did it on work hours so I thought credit is in place.

RTL users, please try it out and notify me of anything.
