This adds the level header parameter NightsTime, which allows setting mare-specific time limits. It takes a comma-separated list of numbers, similar to the Grades# parameter. If a mare's time limit is set to 0 with this parameter (which is the default case), it will be taken from the Ideya Drone as usual.
Example: NightsTime = 100,120,80 will set the time limits for mare 1, 2 and 3 to 100, 120 and 80 seconds respectively.
