Log Message:
syncalert: merge REDALERT.INI instead of clobbering it

door_setup_engine_paths() rewrote the per-user REDALERT.INI from scratch on
every launch with only a [Paths] section. That wiped the engine's own
persisted settings (music/sound volume, etc.) each session, and left
[Intro] PlayIntro absent -- so it defaulted true, Special.IsFromInstall
stayed true, and the door auto-started a Soviet campaign game on Normal
every session instead of showing the main menu.

Now merge with xpdev's INI reader/writer: read the existing file, (re)write
only the runtime [Paths] UserPath/DataPath, and seed [Intro] PlayIntro=false
ONLY when it is absent. So a fresh install boots to the main menu (with the
Allies/Soviet and difficulty choosers), a sysop's or the engine's own later
values survive, and iniWriteFile() rewinds+truncates so everything else in
the file is preserved. Existing broken per-user INIs self-heal on the next
launch.
