changeset 3871:da838f6e04a2 draft

(svn r4911) -Fix (FS#156): The Ai no longer attempts to build signals under bridges. NOTE 1: Remove/revert this for the bridge branch NOTE 2: Bug displays fundamental flaw in command system: If two commands, where command 2 depends on command 1, have to be checked, all those checks need to be manual. (like in this example, first build rail then build signal. BuildSignal cannot be checked without DC_EXEC as the rail isn't there yet)
