LibWeb: Replace some TODO() calls with FIXME comments in EventHandler

Browse source 
This patch downgrades some TODO() calls when the cursor in an editable
DOM node should move to the previous or next node. Previously, the
process would crash, whereas now, the cursor will just stay where it
was.

This seems more sensible for now, as there is no reason to crash just
because of this.
