Modularization of Panel App

Added the abilities for the config.js file to the panel and this
required the additional route for queues/fetch to
mod_callcenter_routes.inc
Queue Agent DND Button Function
Added the status check for a agent to see if their state and status is. Added output to the post so the user knows if it was correctly set or not
Working on getting the Modular Config.js file working in the panel
fixes for the javascript error that currently happens, when loading the configuration js file
fixes and tweaks about the js and missing fetchQueues function
Adding the changes from stash
fixed the Panels config.js issues and is now working correctly
