Add datetime to window title

[IanButterworth]

Implements #194 but instead adds it to the end of the window name, even if a custom one is provided.

I think knowing the order that windows were opened in may always be of value

Closes #194

I can go with this. I worry a bit about the cognitive load of comparing times, especially if the user has gone to the trouble to give each window a unique name anyway (now we're adding a distractor with no new information).

[IanButterworth]

That's a good point. How about it's only shown for @profview given there the API isn't currently exposed for setting the window name? I think that might make more sense than appending it to a ProfileView.view() anyway because I think the time is informative wrt. the data collected, not when the window opened.

I'll give this another go

[IanButterworth]

Updated. Also, I don't feel strongly about this. Just an idea. I'd be happy to leave it out

[timholy]

I like it. Let's do it.
