Add Helper Maker

[Zoinkwiz]

This is intended to allow for players to make very simple helpers which they can share with one another, such as small guides.

It works off allowing JSON to be made, which can be interpreted as a QuestHelper via JsonToQuest as a JsonQuestHelper.

Expected fields and constants are defined in JsonConstants, StepParameterDefinitions, and RequirementParameterDefinitions.

A UI exists to make the creation process easier than editing flat JSON.

The general structure of this is:

• A list of Requirements
• A list of Steps, which can make use of requirements for their panels (usual green/red)
• A list of actual Steps (QuestSteps, needs a name change), which are effectively just instances of each Step as a Requirement/Step combination in a ConditionalStep.

Each step of the ConditionalStep is then a section in the sidebar, with the locking capabilities enabled by default due to the assumption any of these steps may be buggy.

Notes:

• Very ugly, needs UI work
• We're importing data. It should be safe, but worth considering any potential security issues that could arise
• No concept of saving a helper, you'd need to keep the JSON handy and import each session
• Can this be abused to allow for highlighting things against the Third Party Guidelines?
• We should get some proper tests going for this
