Altscreen enter and exit messages about bubbletea

That would be awesome, @kiyonlin. Please do feel free to submit a PR. I’d probably call them tea.EnterAltScreenMsg and tea.ExitAltScreenMsg for naming consistency (like tea.KeyMsg and tea.WindowSizeMsg).

[kiyonlin]

This is a good idea. So we should provide 2 Msg tea.EnterAltScreen and tea.ExitAltScreen. User can trigger them in Update if they want to change the alt screen mode.

I think I can submit a PR if you haven't done this.

Actually, @kiyonlin, there’s a branch I should merge before you do this. I’ll do that in a few minutes and let you know when it’s in.

[kiyonlin]

Dw, I will do it tomorrow (9 hours later) 😃

@kiyonlin Alright, go for it. There are some small changes in how the alt screen is set in #61 (just merged) but it shouldn't change your implementation.

Oh, just one more thought: realizing we'll also need two commands in addition to messages which I'd probably call tea.EnterAltScreen and tea.ExitAltScreen.
