Small fixes

In the beginning of the intro level, mayor stood up automatically due to an AI mistake

in windowed mode, window size was reset to screen size on scene load

getting to climb ladder at the beginning of first mission was difficult, now player snaps to the ladder automatically

made it a bit more difficult to skip the climbing part of the tutorial

made cranes not useable since they're just confusing and I haven't figured out a way they'd be useful

walking over bodies is easier when ceiling is low

throwing indicator and "ready to throw" animation got stuck in some situations

preventing jumping when ceiling is low (to avoid some bugs)
