measure time and calls with sequel

I've ran that code in one project (not on production yet) with both, ActiveRecord and Sequel, enabled. Seems to work fine:
``Completed 200 OK in 281.4ms (Views: 0.522ms | ActiveRecord: 5.551ms(1q,0h) | REST: 263.257(3, 3) | Sequel: 0.681ms(1q) | GC: 0.982(0) | HP: 0(999600,6023,157952,426406))``
