Wrong dialog for blocking of group
When blocking a group, a dialog with these writings appear:
You are about to block a contact. Are you sure you want to continue?
This contact will see you offline and you will not receive messages he will send you.
☐ _Do not ask me again
Proposed:
You are about to block a group. Are you sure you want to continue?
Contacts in this group will see you offline and you will not receive messages they will send you.
☐ _Do not ask me again
I think this English should be improved. Window titles are missing, too.
