[D11] wait for the bootstrap to complete a bit later (last possible point at the current time). This means if you choose a server before the UI has finished loaded you won't get a loading screen (being fixed currently), also if you do it too soon, the server authentication could time out (just waiting on running servers to upgrade to enable keep alive), but at least the server menu is responsive and the overall flow is bit more overlapped. As the warmup bundle is optimized the potential for having to wait for the loading will narrow to hopefully an acceptable level.
