#
# This is the interface for agents to chat with customers and each other.  It's separate from the manager-to-agent 
# chat interface out of necessity and calls the chat_db_query.php page to send information and display it.  It will
# display any open chat the agent has, and of those open chats the full conversation of the current active chat 
# will be displayed.  It will also show when an agent has a new unread message in any of his conversations and
# allow the agent to toggle between them.  They can also initiate chats with any agent currently logged into a
# campaign through the agent interface.
#
# Builds:
# 150903-2349 - First build
# 151213-1107 - Added variable filtering
# 151218-0913 - Added missing translation code and user auth
# 160303-0051 - Added code for chat transfers
# 160818-1235 - Added line colors and scrolling
# 170528-1001 - Added variable filtering
# 190902-0914 - Fix for PHP 7.2
