Use CAmount for amounts
Use CAmount rather than unsigned int for amounts for consistency
with other fee rate amounts.

This does change the type from unsigned int to unsigned int64, and
while it is unlikely anyone would need a dust limit higher than
unsigned int, again this ensures the theoretical maximum is in line
with other rates.
