improve send selection

[yuuuxt]

Thanks for creating this extension!

I want fsi:send selection to send the complete lines selected, instead of selection only. It's easy to have an incomplete selection (e.g. omitting o of first-line open System) using mouse. So I made this naive PR.

Now we can just briefly select the lines (don't need to be complete) to send the complete lines.

It works like this:

I think that the idea of improving selection is a great one, but worth noting that with this Ionide looses a feature of selecting something mid line and evaluating it. I'm not sure if it is a big deal.

I could imagine that I want to select one of the parens and evaluate the middle, with that change it would always evaluate the whole line.

My idea of solving this problem, that I want to explore is to provide a shortcut for evaluating paragraphs.

let s = 0

let a = 1 // middle
let b = 1 // section
printfn "%d" <| a + b // middle section

let c = 1

Placing a cursor anywhere in the middle section (commented) and evaluating would send the:

let a = 1
let b = 1
printfn "%d" <| a + b

To REPL

@jasiozet Yes, it is better to have a new shortcut to behave like this and keep the original one unchanged.

For me the original behavior is not useful and modifying it makes minimal effort, so I did it like this and started using it.

Your execute-paragraph idea is one more step further :)

I also created #1728, maybe we can let discussions happen there?
