Add logic to flush channels, and to safeguard adding of events, aftermain loop in Application.Run exited

Thanks for this!!!

I just started trying out this library and after seeing the done guard application.go:380 I honestly have no idea what the point of QueueUpdate{,Draw} was because the there was never anything setup to be on the other side of the channel to pump something so it can drain... and because it relies on a message it received rather than the status of the channel, closing it is useless too... That change was made 13 months ago... has it been broken that long?

Hi,

From the examples, and the general use case, the tview/Application will always be in the main method and will cease to exist, when the application terminate.

In my use case, I am using the tview/Application to manage a reader/writer stream from a SSH channel. This is a bit different from the general use case, and my application does not terminate when the SSH / tview/Application terminate. I need to close and drain the channels, to clear resources.

I removed some of the done guards, as it was excessive. Can not answer you on QueueUpdate{,Draw}
