LibGUI: Add Ctrl-U to insert mode

Browse source 
While under insert mode, Ctrl-U deletes all characters between the first
non-blank character of the line and the cursor.

Implement delete_from_line_start_to_cursor() in TextEditor. Then, call
the method in VimEditingEngine via its pointer to an instance of
TextEditor.
