gamja settings can be overridden using URL query parameters:
server
: path or URL to the WebSocket servernick
: nicknamechannels
: comma-separated list of channels to join (#
needs to be escaped)open
: IRC URL to opendebug
: if set to 1, debug mode is enabled
Alternatively, the channels can be set with the URL fragment (ie, by just appending the channel name to the gamja URL).
