[Rails-devel] 18AL (almost) completed

[Erik V. <eri...@hc...>]

I have added the following features to 18AL:
- the NDY special ability to buy a train at half price.
- the destination ("historical objective") bonus.

This completes 18AL (with one exception, see below), 
and I have upgraded its status to "Fully playable".

The missing bit is the ability to trade private companies
between players. This feature also exists in 1830, but nobody
has complained so far about its absence, so I guess there is
no high demand for it. Indeed, I have never seen it used, 
and the 1830 PC game does not allow it at all.

It will have to be added one day, but I consider it low priority.

Two more things to report:
- I found that each individual class that can serialize itself
to the save file needs its own serialVersionID. 
I have added that to all relevant classes. 
The consequence is, that old save files cannot be loaded any more.
- Fixed a bug: payout for shares in the Bank Pool did not work (also in
1830).

Next I think I will work on 1851, which is relatively simple,
but adds the important feature of incremental capitalization.

Then it may be time to turn to bigger challenges, such as 1835 or 18EU.
