Refactor script_game_object money functions to use u32

[AMS21]

Since CInventoryOwner already stored money as a u32 it only makes since for us to also treat it like one.

Also fixed a logic bug which would have allowed the object to transfer money which it didn't have.

Since both values are unsigned subtracting them from another will never
produce a negative value.

This bug was also present before changing the function signature since the money
variable was implicitly converted to an u32 resulting in the same problem.

So, does that fix #1173 by the way?

Well not really. You don't get negative money. The money transfer just does not happen but the dialog still works and you get the information just without losing money.

It does produce a LUA error now so the check definitely works:

! [LUA]  Character does not have enought money
stack traceback:

Any objections to getting this merged? :)
