Small fixes — Gust of Wind Steam update #507908

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)
