Effectively make all XCP fees dynamic based on the ratio between the transactions of a given type seen in the last difficulty period and some hard-coded target value. If there are fewer transactions than the target, the fee should be very low (zero?); if there are more, then the fees should start to increase, say logarithmically. We'll want to implement this for #1939 at least; possibly other things.

Note: This will need to be tested carefully.
