Handle currencies customization

[ludofleury]

Hey,

Actually, I want to add a new currency, for example: facebook credit.
I have many options:

1 Do not rely directly on Money.
* Custom\Currency extends Custom\Currency override the __construct.
* Custom\Money extend Money\Money override the __construct and the __callStatic replace the Currency typehinting by a Custom\Currency

2 Rely on Money

• Use the Currency and add my custom currency data into the currencies file
• In the first case, it looks a bit overkill but maybe it's the best practice (I would love a feedback)?
• In the second case, it's straightforward yet it requires a hack in currencies.php file which is not versioned but live in the vendor dependency directory (and that sucks).
  Can we rely on a global var / path ? some other stuffs ?

#58 implements some sort of repository for currencies. You will be able to use custom currencies, but it will be your responsibility to check whether a currency is "real" or not. (By the definition of value object validation will be no more part of the Currency implementation)

#58 Implements a decent logic for solving this issue. None of the mentioned solutions can be taken into action. IMO became invalid.
