The menu works with HTML/CSS only, and JS support will also allow
closing it by clicking outside of it (instead of closing allow when
clicking on the menu icon again).
This commit updates the dark theme by FlamingKite, and adds a
simplemde-override.css file which overrides most of SimpleMDE's styling
for the edition area (CodeMirror) to replace fixed, bright-style values
with references to theme variables.
