* A command handler use the parameters to act according to the meaning of the command.
* The tile parameter defines the tile to perform an action on.
* The flag parameter is filled with flags from the DC_* enumeration. The parameters
* p1 and p2 are filled with parameters for the command like "which road type", "which
* order" or "direction". Each function should mentioned in there doxygen comments
* the usage of these parameters.
*
* @param tile The tile to apply a command on
* @param flags Flags for the command, from the DC_* enumeration
* @param p1 Additional data for the command
* @param p2 Additional data for the command
* @param text Additional text
* @return The CommandCost of the command, which can be succeeded or failed.
