Item price units

[judgej]

The extended Item class assumes that the price for each item is supplied as minor currency units. There is not consistent documentation that states how item prices are supposed to be supplied, but I suspect it is major units in most other gateway drivers.

I think it is going to have to change to major units to be consistent with the overall amount for the transaction.

For reference, the question about the currency units was asked here:

https://github.com/thephpleague/omnipay/issues/380

The solution is to accept the following as equivalent:

• 123 (integer, minor units)
• 1.23 (float, major units)
• "123" (string, no dp, minor units)
• "1.23" (string, with dp, major units)

Fixed and working.
