Pool reward formula jumps at epoch 3650

[lyulka]

Protocol version: 0.4.0

At n = 3649, this formula evaluates to 0.00004506712. At n = 3650, this evaluates to 0.00004109589, an over 9% difference:

The intention was for the transition to be smooth, but in converting the early issuance formula (which specified a per-year rate) into the implemented issuance formula (which specifies a per-day rate), the n < 3649 formulae was modified without adjusting the n >= 3650 formulae.

This is not critical.
