MicroHs is the browser is more fun now

I’ve updated MicroHs in the browser. New features:

• You can import a local directory into the in-memory file system used by MicroHs. It will keep in sync with changes made to the local directory (with a small delay).
• You can import an entire source tree from GitHub.
• There’s a simple graphics package, CanvHs, inspired by Gloss and Shine.
  • There are some demos. You’ll be told on startup how to run them.
• A few utlity functions: ls, cd, cat

Comments welcome!

A warning to those allergic to clanker code, a lot of the new code was written by Gemini.
