Basic applets for MVP

[mathkimchi]

For MVP, need to do:

• Text Editor
• File Explorer
• Something that parallels a browser (fake browser or documentation reader)
• Presentation viewer (I have a cool plan for doing something with this)
• Command hub

For the documentation reader, here are some relevant TUI apps for inspiration:

• Lynx terminal web browser
• Tui Wikipedia reader which just so happens to be in rust
• Bat which is like cat but with syntax highlighting (works for Markdown) and also happens to be rust
• Glow terminal md renderer

As you can tell from subissues #24 and #29, I am 0 for 2 with embedding existing applications.

I think I'll work on the command hub.
