Complete ISO list

I reckon I should add the non-standard "currencies" that are currently excluded, but implement some methods to easily distinguish them or filter them out (by default).

So what is 'non-default'? Like Bitcoin or just not 'official'?

[alcohol]

The ones listed in the README as "excluded". They are not actually currencies, but more like trading units and such. Possibly used on stock markets and the like.

[barryvdh]

For my case, it doesn't matter as long as they follow the same 'rules', eg. have an exp/numeric code.

These currencies are absent:
996 -- ESA -- Spanish peseta (account A)
222 -- SVC -- Salvadoran Colón (colón is out of circulation)

@kashukov ESA is historical and not part of the current list. SVC seems to be missing indeed.
