v0.2.1 polish: pull Game.SkipIntro from the F10 menu (breaks audio)

User spot-check of the v0.2.1 draft found that enabling Skip intro breaks
audio. It was already off by default (D216); removing the menu row so
players can't enable it until the audio interaction is root-caused. The
config var and lv.c hook are untouched (dead unless an existing ini already
has it set).
