Improvements in focus management of Check names operation
(fixes NB#59427).
* src/widgets/modest-recpt-editor.[ch]:
* New method (modest_recpt_editor_has_focus). This is used
to be able to know if a recipient editor text view is
focused.
* src/maemo/modest-address-book.c:
* Removed all recipient editor focus management. Now we rely
on the window implementation.
* src/maemo/modest-msg-edit-window.c:
* Now we set focus of the failing recipient editor in check
names if it fails.
* If check names does not fail, and focus is in a recipient
field, it does not change the focus from them to to: field.
