multiple channels / chats

[dervondenbergen]

Pass an array of room names to gitter.room in the config instead of a string.

Code has to be changed to listen to all channels and put the right gif in the right channel.

This would enable the possibility to set up only one giphy-gitter instance for multiple channels. Right now there has to be a new an instance for each channel.
