Cover fees optional, return breakdown of fees

BREAKING!
Instead of returning an integer of total fee, we now return a fee breakdown:

{
  totalFeeAmount: number,
  applicationFeeAmount: number,
  providerFeeAmount: number
}

Also added a coverFees parameter that allows you disable the covering fees mode. Defaults to true, for backwards compatibility.

Switch to cents

BREAKING: all amounts are now in cents, to be more inline with Stripe's recommendations for handling currencies.
