[FIX] web_editor, *: properly remove DOM portions in a snippet

* website, website_mail_channel

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, ...).
