Only show item card once when clicked multiple times on the sheet

I noticed my almost never using the buttons inside the chat log for attack rolls (to much work to move over there.. )
But this way the chatlog gets spammed with mutliple "Shortsword" item cards, even if only one is needed.
Idea:
Try to detect multiple attacks with one weapon and only display the item card once.

Implementation idea:

• Hook onto preCreateChatMessage
• Check if its an item card
• If yes, save it as last sent item card
  Now when someone uses an item:
• Has an attack?
• If yes, was the last sent item card this item?
• If yes, only render the attack template, else render both.

Start by locating the preCreateChatMessage hook and the item-card and attack-template rendering paths. Trace how an item attack creates chat messages, then verify that repeated attacks with the same weapon render one item card while still rendering each attack template.
