Double checked @control command functionality: seems to work fine now. cmd_control(...) commented thoroughly. Fixed HelpCommand's use of Pager so that you see the first part of the help file now without having to type both 'help command' to get the file and 'view' to see the relevant part. Also kludged the code a little so you always see displayRows worth of lines. Being at the end means you see the last 25 (i.e. the 25 lines that includes the last lines). Updated some help files.
