Markdown (#214)

* Add basic markdown support site wide

* Improved MD support.

Add some styling for images in MD

Add support for the bastardisation of the MD html for RML.

* Add processing for <ul> in RML

* Add OL processing to RML

* Fix a bug with squares appearing around the last page number

* Remove rml formatting in event_detail

* Improve handling of code blocks in RML

* Add MD to rigboard

Reduce MD title sizes as they were offensively large

* Add parsing of markdown when editing event items

* Improved list handling in RML

* Add tests for markdown support.

Focuses mainly on RML as that's where it will break

* Add indications of where MD support is enabled as per comment by @samozzy in #178.

Isn't quite a full description, but for the most part this should be enough for the people who know how to use it see where they can use it.

* Add failing test for markdown processing none

* Fix for failing test in e0d56e

* Add failing test for using single line breaks as per comment on #214

* Enable line break extension for single breaks in paragraphs by new lines.

Pass tests in ef3de607c3

* Enable GH flavour linebreaks in JS rendered markdown

* Made RML bullets pretty :)

* Added WYSIWYG editor. Works for notes & description, fails miserably for items :(

* Fixed for event items. Will probably fail tests because selenium can't type in simpleMDE :(

* FIX: Re-enable markdown on paperwork

Strikethrough is broken in all sorts of places for whatever reason

* FEAT: Markdown support on asset comments

* FIX: Prevent js injection through markdown fields

* Initial fixes

* Basic dark theme for simplemde

* Swap to locally delivered SimpleMDE

* Region for selenium testing of SimpleMDE

Bleh, Javascript all around

* Tests passing!

Fixed not using region for item modal, and overflow error on paperwork with really long description. Looks junk but I'm not really bothered

* Pep8 fixes

* Fallback for null HCapatcha sitekey

I.e. when we're on a branch

* Fix item description print being broken

* Actually fix sitekey problem

* Fixes for using markdown in asset comments

* Properly initialise markdown on asset comments
