Add Ajax to check-in/write-up

[ArnautDaniel]

Move to card system instead of dataTables

[ArnautDaniel]

Need Ajax in a few specific areas

Checking in or partially checking in items.
--It should grey out the card and show a toast message that the item has been checked in
--It should unreveal the card if a partial checkin was done and show a toast

Writing up an item or removing an item from the invoice:
--Should automatically place the item into a card and show the next image
--Should grey out the card if removed until next refresh (an undo would be nice)

Ajax now works except for one specific issue but that'll get fixed later.
