Support ^e and ^y

Vim has some nice scrolling features where the cursor stays in the same spot but the screen moves up and down: ^E and ^Y. From scroll.txt:

                                                        CTRL-E
CTRL-E                  Scroll window [count] lines downwards in the buffer.
                        Mnemonic: Extra lines.

                            CTRL-Y
CTRL-Y          Scroll window [count] lines upwards in the buffer.

@jordanlewis oh your workaround is neat! didn’t notice Code already supports line scrolling, then it will be easy to add these command natively in VSCodeVim. I’ll add this real quick.

^d was also not working (It was assigned to ‘delete right’ ). I’ve added the following to @jordanlewis’s answer:

    {
        "key": "ctrl+e",
        "command": "scrollLineDown",
        "when": "editorTextFocus"
    },
    {
        "key": "ctrl+y",
        "command": "scrollLineUp",
        "when": "editorTextFocus"
    },
    {
        "key": "ctrl+d",
        "command": "extension.vim_ctrl+d"
    },
    {
        "key": "ctrl+u",
        "command": "extension.vim_ctrl+u"
    }
