Many changes, most importantly: Chrome user script to enable auto-loading and auto-refresh.

* Chrome user script.
* Disable easter eggs by default.
* Abstraction to retrieve getUsername() (so configs don't rely on API)
* Now using "ChunkBotConfig" global to allow direct override of config after config is loaded.

Removed:
* Special command to allow bot to respond to people addressing it directly.
Updated documentation to reflect both 1. To Do list and 2. Change Log.
