Early October Updates

[EthanThatOneKid]

• Added HTML to the homepage.
• Added a static middleware (/std/server/middleware/static.ts) for the server.
• Added dict modifier functionality (ex: dex: dict % <number, PokedexEntry>).
• Updated the Pokemon example (/ex/pokemon/).
• Added TypeMap to the Cartridge registry since each Cartridge must have a dedicated code cartridge, typemap, and mime type in order for the server to correctly generated the requested code.

Resolves #7. Resolves #24.
