Subject: [PATCH] Support darkplaces.opt from local files too.
If both are present, flags from both get prepended; the execution order is:
[attached darkplaces.opt] [local darkplaces.opt] [command-line flags]
Also added flags -noopt (don't parse darkplaces.opt) and -noselfpack (don't read attached pack).
