Subject: Made some changes from review comments: - Made LoadKernelSystemMode
 return a pair consisting of a system mode and a result code (Could use
 review). - Deleted ErrorOpenGL error code in favor of just having
 ErrorVideoCore. - Made dialog messages more clear. - Compared archive ID in
 fs_user.cpp to ArchiveIdCode::NCCH as opposed to hex magic. - Cleaned up some
 other stuff.
