Compatibility with modern hubot API.
Remove hard-coded id; if this was originally intended to cause the bot to ignore itself, then a better approach should be sought!
correct github paths; bump version number
Merge branches 'fix/modern-hubot-compat', 'fix/remove-hardcoded-ignore-userid' and 'fix/correct-package-metadata'
Various significant refactoring including: reply to channel that request was made in; subscribe automatically to all channels (obsoleting HUBOT_KANDAN_CHANNELS parameter); better error handling; ignoring messages from ourselves by knowing who ourself is; subscribe to new channels that are created, unsubscribe from channels that are destroyed.
