Fix maps variable in OfficialChallengeHashes not being global (caused error in normal Racer)

Fix hedgehog being able to make walk/jump sounds before it was placed If in hog placement phase you select Skip and then pressed the walk/jump keys, you heard sounds although the hedgehog is not placed yet.

Ignore gmTimer after attack or hog is no longer controlled You were able to set the timer after you threw a grenade

Clear gmSwitch before activating switcher If if you pressed [Switch Hedgehog] key and THEN enabled the Switch Hedgehog utility, you immediately switch. This was mildly confusing.

use locale rules for the challenge hashes

restore old land hashes which in theory should not have changed in .24

Separate synced pixels from land digests - this is mostly to allow the official racer digests to remain unchanged.

Add exit hint after Basic Movement Training

Easier back jumps in Basic Movement Training (fixes bug #692) The explanation of Back Jumping (2/2) has been simplified and the "hard" part has been made easier by lowering the girders. The original idea was that I wanted to force players to learn how to jump higher by delaying the 2nd backspace keypress. But this turned out that this section was too unfair and we have lost at least one player due to rage-quitting, according to feedback.
