Move the help html to a template and populate the lists dynamically.
This also splits out the base HTML stuff (eg, the <html> and <body>
tags) to a base template file.
When typing @ a div will show up with all the chat names that match.
When up or down arrow keys are pressed, the highlight changes.
Tab handling is currently incomplete but the event is prevented.
issue #7
Removed two fmt.Sprintf() calls and a fmt.Printf() call. The Printf()
was for debugging and isn't needed anymore. Sprintf() apparently
isn't all that performant.
Implement some commands in the wasm client code:
- /playing (setting and clearing)
- /refreshplayer
Commands not yet implemented:
- /purge (command doesn't exist yet on server)
- /help (doesn't open window)
