FIX: Compile issue in Windows with the command line server
VERSION: Step to 11.7
FIX: Crash after deleting a stop in some cases.
REVERT: "If a rail type convoy had its route unreserved, another convoy could enter its space and collide with it": this caused more problems than it solved.
FIX: Choose signals did not work correctly in some cases
FIX: Crash when altering schedules in some particular circumstances.
FIX: Incorrect counting of upgradable vehicles in the replace dialogue.
CHANGE: Slightly reduce severity of impact of hills.
CHANGE: Load/save the check_waiting parameter in network games (and prepare to do so in all games when the major version is stepped to 12). This should provide slightly more consistent timing of waiting time recalculations when games are saved/reloaded, although will mean that games saved in network mode from recent versions of Experimental will no longer be able to be loaded.
PARTIAL REVERT: Saving of check_waiting only when the major version is 12.
