Item/Entity/Text Embeds

[Erdragh]

Implements:

• Item embeds if a message has a Component with a SHOW_ITEM hover action
• Entity embeds if a Component has a SHOW_ENTITY hover action
• Text embeds if a Component has a SHOW_TEXT hover action

Embed colors are decided by:

• Item rarity
• Text embed Component color
• Green if entity is passive/friendly

This will also implement:

• Allow blocking malicious messages #20 (Allowing blocking malicious links in Minecraft messages)
• Make links sent in discord work as links in minecraft #19 (Allowing links sent into Discord chat work as links in the Game)

I now parse Discord messages as Markdown and render them into Minecraft's Chat Component system. This system may break so I expect there to be more issues coming in. I've tested what I could.

There's one thing left I want to do, which is adding more configuration options for the rendering.
