(svn r1323) Adding autoreplace feature
This feature works much like autorenew, but it will get you a new engine type instead of a new one of the same type. Once
ordered, it will automatically replace the engines while they visits a depot. The GUI for setting this up have been added on the
vehicle overview windows
Note: autorenew is now autoreplace, but to the same engine type
Nice new features, that was added to make this possible
- windows can now have two independant vertical scrollbars
- CMD_SHOW_NO_ERROR have been added as a flag for DoCommandP. It will make it do the action instead of showing the red box with
estimated costs even if shift is pressed
- fixed problem where enginetypes where not initialized when loading a game. It's now done in InitializeGame()

// This pretty simple file checks if the system is LITTLE_ENDIAN or BIG_ENDIAN

     4

//  it does that by putting a 1 and a 0 in an array, and read it out as one

     5

//  number. If it is 1, it is LITTLE_ENDIAN, if it is 256, it is BIG_ENDIAN

     6

//

     7

// After that it outputs the contents of an include files (endian.h)

     8

//  that says or TTD_LITTLE_ENDIAN, or TTD_BIG_ENDIAN. Makefile takes

     9

//  care of the real writing to the file.
