Support pasting URLs over selection text in the textarea editor. Does not work in EasyMDE and I don't intend to support it. Image paste works as usual in both Textarea and EasyMDE. The new `replaceTextareaSelection` function changes textarea content via [`insertText`](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand#using_inserttext) command, which preserves history, e.g. `CTRL-Z` works and is also demostrated below. We should later refactor the image paste code to use the same function because it currently destroys history. Overriding the formatting via `Shift` key is supported as well, e.g. `Ctrl+Shift+V` will insert the URL as-is, like on GitHub.
