Added SyncPackages method. Can be called server and client connection.
In first case it begin synchronization of packages with all clients.
In second case client send message to server to begin synchronization of packages with all clients or with only this client.
Check changes in required packages before sync.
All sync method replaced by void Connection::SendPackageToClients(PackageFile* package) may be called after Scene::AddRequiredPackageFile on server
Merge remote-tracking branch 'remotes/cin/master'
Minor editing of comments.
Changed Connection::SendPackageToClient() to not broadcast to all clients. Instead Network::SendPackageToClients() will send to all clients in a specific scene. Updated Network Lua bindings.
