you could comment the corresponding lines out, by // PrintToChat...
Simply copy parts of the chat into the search window in your editor and look for the corresponding code line. then you put "//" in front of the Print... .

Edit:

PrintToChatAll("\x03[JBTP]\x01 \x04%N \x01has been swapped with \x04%N", swapplayer1, swapplayer2);
change to:
//PrintToChatAll("\x03[JBTP]\x01 \x04%N \x01has been swapped with \x04%N", swapplayer1, swapplayer2);

Same for all other "PrintToChat..." in the code.
