Insert UI Extension Snippets at the Cursor

When creating a UI extension, the snippet generator can be an invaluable tool.  A small enhancement to this tool may make working with it even more enjoyable. When clicking the Insert Snippet button in the UI extensions form, the snippet is no longer created at the bottom of the existing HTML, JavaScript or CSS code, but right under the position of the cursor.  This makes creating and maintaining complex UI extensions just that little more user-friendly.
