Added middleware for parsing channels
When a request's text contains any valid channel names, it will find them and add them to the request under .mentions.channels
it will be an object where each entry is a matched channel name, the key will be the index of where in the request text the channel name begins
Added coc handler config to the config sample
Removed autojoining on request from the nodebot lib code
Removed the middleware test and added the channel parser
Replaced hardcoded config with values from the config file
