(svn r6680) -Codechange r6679: [train build window] only generate the list when the window data is invalidated or the window is generated, not on each redraw

(svn r6679) -Feature: [train build window] added filter for wagons, engines or both in the display
-Codechange: [train build window] to get rid of a really ugly hack, the train build list is now generated in one loop and stored in an array

(svn r6678) -Code cleanup: [train build window] made an enum with widget names and fixed some incorrect indents

(svn r6677) -Codechange r6651: [depot window] disabled the check for the correct cache in the depot window
Nobody had problems so far, so we can assume that InvalidateWindowData() is used everywhere where it's needed
The check is just disabled, not deleted so it's quick to reenable if we change some code and wants to check this again

(svn r6676) -Fix: [vehicle list windows] mass start/stop now works correctly in shared orders and station lists
