Alpha: TTDPatch 2.0.1 alpha 9

Hi all,

I've released alpha 9 at http://www.ttdpatch.net/src/

It doesn't actually contain any code from myself, but Csaba has contributed 
a few new features instead.  I'm in the final stages of writing my PhD 
thesis and basically don't have any time to do anything except write write 
write... (and that's writing the thesis, not TTDPatch code unfortunately :) 
) so I won't be able to fix bugs or add new features until that's over, 
which it will be on January 5th (for better or for worse).  So if you send 
me an email, don't expect a reply soon :).  There won't be any more alpha 
versions from me until then, although I'll still publish one if I get code 
submissions from the other developers, such as this one.

Anyway, apart from improving some existing features and fixing bugs, Csaba 
has also added four new switches that enable a warning message whenever a 
vehicle is lost, which means if it hasn't visited the station next on its 
schedule in a given number of days.  The number of days can be set 
individually per vehicle type, because ships usually take a long time to 
get to a station, so that they shouldn't be considered lost just because 
they're only halfway there.

For the full list of changes, please see below.

All changes in 2.0.1 alpha 9:

     below it
