Implement NetworkManager

For now there are two methods: - `NETWORK:IsUrlAllowed()`: Check whether access to a certain URL is allowed. - `NETWORK:HttpRequest()`: Perform an HTTP request. By default access to the network is disabled for all target hosts. It can be enabled by setting `HttpEnable=1` in the preferences. Individual hosts have to be added to `HttpAllowHosts` as a comma separated list to allow access. See included docs for more details on usage.
