v6.5.3: Don't consider PvP .entities files online-safe (#9)

Fixes a false positive with some mods being erroneously considered online-safe, by making .entities files go through the same path checks as generated/decls/*.decl files.

The "/maps/*" whitelists were changed to "maps/*" (without a slash at the start) so that they'll also match (online-safe) .entities files, and "maps/game/horde/" was added so that Horde .entities files are still considered online-safe.
