Title: ActiveSupport-like business_days counting

Two big changes in this PR:

* `workday?` and `weekday?` method are now instance for time and date classes
* `#ago` and `#since` methods for BusinessDays class works as ActiveSupport analogues, returning the same class as was passed. `Time.current` used by default
