Cargo rate should have selectable units

[GoogleCodeExporter]

Currently, SwitchList requires that cargo rates be in (integer) cars per week, 
which is good for allowing occasional cargos (1-2 cars a week) but bad because 
it requires users to do lots of division in their heads to convert between cars 
per week and the likely number of cars on a siding each day.  It's also hard to 
give rates less frequent than once per week for users who host lots of 
operating sessions or want more rare occurrences.

One solution would be to allow car rates to have different units "per day", 
"per week", "per month", and allow the rate value to be a floating point 
number, allowing "2 cars per month" or "1.5 cars a day".

Requires changes to database schema, UI, cargo assigner code, and reports.

Database changes and day/week interface went in at r424.  Still need to change 
cargo assigner (and other code) to handle per month rates.
