WIP: maybegetitem

Description

This MR replaces all instances of getitem and inventoryplace with a function that combines both: maybegetitem.
The function only gives items if ALL of them can be carried by the player, otherwise displays an error.

Usage

Normal items:

maybegetitem ItemName, amount,
             ItemName, amount,
             ...;

Special items:

maybegetitem ItemName, "amount,identify,refine,attribute,card1,card2,card3,card4",
             ItemName, "amount,identify,refine,attribute,card1,card2,card3,card4",
             ...;

Named items:

maybegetitem ItemName, ":name",
             ItemName, ":name",
             ...;

Mixed:

maybegetitem ItemName, amount,
             ItemName, "amount,identify,refine,attribute,card1,card2,card3,card4",
             ItemName, ":name",
             ...;

## Example Before: ``` inventoryplace ItemName, amount; setq Quest, value; getitem ItemName, Amount; ```

After:

maybegetitem ItemName, amount;
setq Quest, value;
