Amount precision

[sevastos]

Due to the nature of number handling on javascript numbers with more than 15-16 significant digits can produce loss of precision.

The best solution to my knowledge is to handle the amounts as strings and use a bignum library for the arithmetic.

+1 This needs to be fixed.

It would be great if you could alter the test suite to properly include the missing coverage, then add bignumber to make the tests pass again.

Hey Marak,
In order to be fully protected from losses it needs to deal with "strings" in and out, meaning that the returned on callbacks number result.amount, result.currencies.BTC.amount and others should be either strings or bignumber instances, but that will be a breaking change.

That's okay, we can make those stings.
