Fix send code for newlines and Radian #114 #117

Fixes #114
Fixes #117

What problem did you solve?

1. When sending code to console (R or Radian), blank lines before the code chunk are also sent (Newlines when sending code to Radian #114).

2. When sending code to Radian console, identation is odd (Messy indentation in console when sending text to Radian #117).

This PR adds a new setting, r.bracketedPaste, which enables bracketed paste mode to fix the indentation problems with Radian. This also works with the R console but not with readline 6 or before, so I have set it to false by default.

(If you have)Screenshot

R with bracketedPaste set to false, using the command R: Run Selection/Line with the cursor on line 3 - note that there is no blank prompt in the console BEFORE

> f <- function(x) {

which shows that no blank lines have been sent:

Radian with bracketedPaste set to true, using the command R: Run Selection/Line in Active Terminal with the cursor on line 3 - note lack of blank prompt, and correct indentation:

@randy3k Could you look at my bracketed paste mode code (lines 106-107 of src/extension.ts)? I think it is fine but you have a lot more experience with bracketed paste mode than I do. Thank you!

It looks perfect to me, except that I only have a little experience with VS Code extensions.

@randy3k Great, thank you. If the bracketed paste mode part looks fine then it should be okay.

@Ikuyadeu This is ready to be merged if you are happy with it.

@andycraig Thank you for your contribution!
Also, you changed README.md and bugreport.md. It is helpful for me.
@randy3k Thank you for your review!

Hi @Ikuyadeu, when you have time would you be able to do a release with this change?

[Ikuyadeu]

@andycraig Sorry, I'm late. I just released the new version now.
