Alpha: 2.0.1 alpha 20

Hi all,

Yet another alpha version is available at http://www.ttdpatch.net/src/

It includes Oskar's latest changes to the canal code, including improved 
dike displays (especially corners and under bridges) and changing the icon 
in the construction window.  For this reason, you need to download the 
updated canals graphics from http://www.ttdpatch.net/newgrf.html

The electrifiedrailways feature has changed slightly, now TTDPatch properly 
supports mixed power trains, e.g. trains with both electric and diesel 
engines.  These trains now use the correct power when on unelectrified 
track, without the contribution of the electric engines.  It also allows a 
train whose first engine is electric to run on unelectrified track, as long 
as other non-electric engines are present in the train.

A small improvement to the "freighttrains" switch stops trains from getting 
overloaded.  As soon as the train is so full that the engine can't pull the 
train with at least half its top speed, the train will stop loading.  Note 
that this doesn't take into account hills, so that the train may still get 
stuck if it has to go uphill.  Mainly this is intended to "help" the AI who 
sometimes build trains with horribly underpowered engines when the 
freighttrains feature is on.

Finally there are some more improvements to the new stations graphics 
support.  Now the graphics authors can make stations use custom sprite layouts.

And that's it for today, have fun!

Josef.


All changes in 2.0.1 alpha 19:
- fixed bug causing random crashes if newstations was turned on
- fixed crash at start when neither of curves, mountains or
   multihead is on
- fixed bug deactivating and showing wrong .grf file if first sprite
   is wrong
- correctly calculate power and acceleration of mixed power trains
   on non-electric tracks

   * improved dike support code, corners and under bridges
   * added support for different locks at sea level and inland
   * changed icon in the ship construction window
- fixed bug with action 0 properties for props>07 not accepting
   numinfo>1
- catch grf error if action 0 doesn't have as many props as
