Stop writing loadorder.txt to prefix, propagate save deletions

deployPlugins now writes only the plugin-list file the game actually
reads (Plugins.txt for PluginsTxt games, lowercase plugins.txt for
FileTime games). loadorder.txt is MO2-internal and never belonged in
AppData/Local/<Game>/; previously writing a stale copy there defeated
LOOT's edits because syncPluginsBack pulled the stale loadorder.txt
back into the profile, and getLoadOrder() preferred it over the
freshly-synced plugins.txt.

syncSavesBack now mirrors deletions: files present in the profile but
absent from the prefix are removed before the copy pass. Without this,
saves the user deleted in-game stayed in the profile forever because
copyTreeContents only copies files that exist in the source.
