Help for settings

There are several lily features that are configurable on a per-user basis via 
settings. These settings can be divided up into different groups:

  Display:   Settings that affect text that is displayed on your screen:        
             unicode, richtext, color, expand_links, or message_echo.           
                                                                                
  Finger:    Settings that affect the information displayed by the /finger      
             command: pronoun, full_name, email, or web_page.                   
                                                                                
  Login:     Settings that affect output at the time the user logs in:          
             auto_review, choose_name, or choose_blurb.                         
                                                                                
  Ordering:  Settings that affect the order things are listed in certain        
             commands: who_order or what_order.                                 
                                                                                
  Sending:   Settings that affect how the messages you send are processed:      
             auto_here, strict_sendlist, markup, or emoji.                      
                                                                                
  Timeouts:  Settings that affect how long you can be inactive before your      
             status changes: idle_threshold, idle_away, or idle_off.
