Editable Disclaimers

[mattxwang]

In this fork, I make the "disclaimer" section editable.

• Cleans up the HTML code for the disclaimer section, removes image background (can be re-added)
• Adds Angular Pipe to "sanitize" html input
• Pipes information from "disclaimer" object in thelist.json to disclaimers, similar to alerts
• Adds GUI in editor page to allow adding and managing disclaimers
• Uses Bootstrap's default link colour to add more contrast
• A few minor adjustments to syntax elsewhere when looking around - big one is that the Primaries tab is now auto-selected

Let me know what you think!
