Before this commit, when using the 'number of columns' option from a
column's snippet editor, the snippet overlay remained floating in the
void if the current column was removed by the option. This was because
the option did a simple "destroy" on the column without caring about
the snippet editors.
This commit introduces a new event which can be trigger_up'ed to ask
the editor to properly remove a DOM portion (destroy related editors,
call the 'onRemove' callbacks, ...).
