Bug: Keyboard shortcuts are not updated after comments are reordered

[bloa]

Description:
When working with a question with multiple comments (say, A, B, C, D), each comment can be triggered through shortcuts Ctrl+{1,2,3,4}.
However, if comments are reordered (into, e.g., B, C, D, A) the shortcut mapping is not updated.
That is, Ctrl+1 is still bound to comment A instead of comment B (the new first comment).

Expected behaviour:
Ctrl+k should trigger the "current k-th comment", instead of the "k-th comment from the initial order".

Additional comment:
The reordering UI isn't very intuitive; drag&drop would feel much better (for a future version)
