[bitcointoyou] Minor change on gitignore.
[bitcointoyou] Fixing a probable bug on nonce, changing from sec to millis. If the user makes more than 1 call / sec it was causing INVALID_NONCE error because the nonce always have to be bigger than the last one. With this change, the user can't make more than one call / millisecond.
