Reworks the `Output` class

[ingrinder]

Description

1. Adds an Entry base class for all of our entries.
2. Reworks output and logos to accept any number of entries.
3. Adds text-wrapping feature/bugfix.

Reason and / or context

1. Allows entries to override their output method to output more than one line (or any output at all) if required.
2. We need to be able to accept >1 line per entry for the above if we add multi-line entries 😃
3. Resolves #63.

@HorlogeSkynet I'd rather you look over this before I go merging stuff into master 😁. Feel free to modify any of it, I feel like the output wrapping is a little messy but I'd like a second set of eyes 👀, after all I have been trying to write those ~30 lines for ~2 hours 😢
