Extending SendingMessage entity to have longer addresses list

Support
#1

Hi

cuba 7.2.20.

For some time now with CUBA it is possible to send one email to several addresses at once, which is good.

However the SendingMessage entity class was not designed to do so, as the address property is limited to 255 characters.

   @Column(name = "ADDRESS_TO")
    protected String address;

Is it possible to extend the entity to add @Lob annotation on the field ? Without losing the current data of course.

Regards
Michael
