SPP loader: Adjust inflation cost scaling on load.

Browse Source 
SpringPP divides all prices by the difficulty factor, effectively making
things about 8 times cheaper. Adjust the inflation factor to compensate
for this, as otherwise the game is unplayable on load if inflation has
been running for a while. To avoid making things too cheap, clamp the
price inflation factor to no lower than the payment inflation factor.
