From 6da5d4c8b55606f614c056932fba43fb730fab5f Mon Sep 17 00:00:00 2001
From: SirStendec <sir@stendec.me>
Date: Fri, 17 Nov 2017 14:59:46 -0500
Subject: [PATCH] Add convenience method for creating CSS variable or setting
 blocks of CSS directly in css_tweaks. Start using those variables for things
 like chat width. Add the ability to highlight messages with mentions in them.
 Fix Sidebar Swap and Theatre Mode. Closes #312
