Followup to e25578d702791bac80b431acd450cc53b6c39a3c Using execCommand to replace the entire contents of the textarea is very slow for larger posts (it seems the browser does a reflow after every 'virtual keypress'. This commit updates the `replaceText` function to be more surgical with its `insertAt` calls. Now it only selects & replaces the characters which are actually being replaced.
