Extended comment loading

[ekarbe]

If a comment chain is too long it needs to be requested.

• Request remaining comment api function
• Apprehend loaded comments correctly

Problem: As of its current state, Reddit-Viewer loads static views into the the webview. So to dynamically add comments you would have to save the current state and append it at the right place.

For now there is no good way to implement this.
