The default environ.ini template (BTWriteDefaultEnvironIni) now carries a
commented BT_GLASS_LAYOUT block in the cockpit section, next to
BT_GLASS_PANELS: off/save/load explained in player-facing terms, noting
glass_layout.cfg lives beside the file and delete-to-reset. Ships commented
out like every other option, so a fresh install still applies nothing.
Verified: Release builds clean; the new text is embedded in btl4.exe.
