Emission Reduction

The initial emission rate is 1 BLB per block. And the emission rate will be reduced by 3% every 9,600 blocks (~12 hours) until it reaches 0.1 BLB per block. (updateEmissionRate function in the MasterChef contract should be called to do it)

This mechanism will greatly reduce the total supply and make our token rarer and help make $BLB more valuable to hold!
