Consider adding [PSConsoleUtilities.TokenClassification]::All member

[oising]

Having to set the background colour with set-psreadlineoption one token at a time is very tedious. While the foreground colours are likely to be different for each token, the background colour is likely to be the same:

ps> set-psreadlineoption -token all -backgroundcolor black

If you don't set the background color for a token, it defaults to [Console]::BackgroundColor. That should be what most tokens use, so it doesn't seem too useful to change the background color for all tokens. Some people might want a different background for just one token type, which is why the capability exists.

I could see having an option to not do any colorization at all, we'll see if more people want that before adding a switch for it.
