Spray can time usage, description reworded


Spray canning or magic markering the floor now takes time. Writing on the floor message length * 2 time.

Changed item description of notes from:
"%1$s on this %2$s is a note saying: "
into:
"%1$s on the %2$s is: "

So you get "Carved on the cooked meat is: I USED TO BE A CAT"
And not "Carved on this cooked meat is the note saying: I USED TO BE A CAT" which was a bit odd.

Writing on objects does not take time. As you can also leave notes on objects in other (non magic markering) ways I and I not know them all. So all or nothing. For now, only writing on floors takes time.
