* Reduce DEFAULT_FALLBACK_FEE to 1,000,000 Koinu. Note this by itself has no effect as the required fee is higher. * Reduce wallet minimum fees to 0.01 DOGE * Update DEFAULT_DUST_LIMIT * Revise derived values after updating recommended fees * Remove fee rounding from RPC tests * Revert tests back to Bitcoin originals where possible
