This adds four new actions:
- `editor::MoveUpByLines`
- `editor::MoveDownByLines`
- `editor::SelectUpByLines`
- `editor::SelectDownByLines`
They all take a count by which to move the cursor up and down.

Example `keymap.json` entries:
```json
{
"context": "Editor",
"bindings": [
"alt-up": [ "editor::MoveUpByLines", { "lines": 3 } ],
"alt-down": [ "editor::MoveDownByLines", { "lines": 3 } ],
"alt-shift-up": [ "editor::SelectUpByLines", { "lines": 3 } ],
"alt-shift-down": [ "editor::SelectDownByLines", { "lines": 3 } ]
]
}
```
They are *not* bound by default, so as to not conflict with the
`alt-up/down` bindings that already exist.
Release Notes:
- Added four new actions: `editor::MoveUpByLines`,
`editor::MoveDownByLines`, `editor::SelectUpByLines`,
`editor::SelectDownByLines` that can take a line count configuration and
move the cursor up by the count.
