Details

The 64-bit money value is being truncated in many places into a negative value, as a result, some features become unavailable, others misbehave.

* If you have more than signed 32bit value of money, you're not allowed to send money to another player, says 'you're not allowed to send loaned money'
* If you try to build something that costs too much, either you're not allowed to do that, or you get income, or there's an error message when the requested action was done correctly, or the action isn't done completely.

Accept I'm testing against current svn, there aren't usually any current svn servers (compatibility checking stops different versions joining), let alone ones that are year 3000.

Just for the record, we are aware of that "bug". It needs a different method of handling the amounts internally. It will be addressed, but not in the near future. I've already started an attempt, but it is a long and tedious process. All versions of OpenTTD are "poised" with that problem. If anyone wants to try and solve the problem, i've included my attempt, which is still a big WIP and WILL NOT COMPILE. Just to show a possible road. Feel free to expand it
