Transaction and fuzzy boundary of filter by date

Created by: yvgithub

Fuzzy boundary of filter by date Filtering with Lower bound 23-4-2015 All transactions of 24-4-2014 are in

Filtering with lower bound 24-4-2015 Just one transaction of 24-4-2015 is in

Same problem as https://github.com/ucoin-io/cutecoin/issues/115

Ok my bad, this is not the same problem as #115 (closed). But this one is fixed. :)
