Behaviour modified from previous. No longer reports ``remaining''
unchecked barrels, barrels are fired in sequence after a random barrel
is chosen following a successful shot.
Corrected winning to use the limit from parameters if one is used.
Moved the limiter to after the sort where it should have been and
reminded myself to look at the entire command not just the first 10
lines.
Added in the 'first' command to get the first line of chat a user spoke upon entry to chat.
Deleted deprecated first.pl script
Added in the 'last' command which is pretty much a copy of first and gets the most recent chatline.
