[feat/core] Add comments

[cjs8487]

Add the ability for players (both logged in and anonymous) to add comments in various locations to leave feedback for game maintainers.

Comments should be able to be linked to the following database models

• Goals
• Games
• Rooms

We expect that room level comments will likely function similar to comments on services like racetime.gg, where players capture their thoughts in on the run as a whole, rather than individual thoughts/suggestions. Those are more geared towards being left on goals directly. Game level comments are intended to capture thoughts on things like missing goals, missing resources, and similar factors.

Comments should be able to left in the following places
Room Comments

• From the room interface

Game comments

• From the game page
• From the room interface

Goal comments

• From the game page (with a specific goal selected in the editor)
• From the room interface

Finally, game maintainers should be able to acknowledge/dismiss comments once they are addressed (or if they will not be addressed)
