Minor Update 7.8.0.5

If a user shares a calendar as "read-ony" with themselves, they cannot un-share/ delete it.

Go to contacts. 
Add Contact
Drag from Personal to > Shared
Drag again and repeat as much as you want

Side note:
Go to global select one or all and drag to personal
Can then add multiples upon multiples of the same contact.

When the CLI update hits this line:
$this->ignorableQuery("alter table txrep TYPE=InnoDB");

It returns this error:
Query failed: alter table txrep TYPE=InnoDB
Reason: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'TYPE=InnoDB' at line 1

Security questions not being validated even though they are correct. No password recovery.

1. Login to A7. 
2. Compose a new email and add some random attachments and also the eml fiel attached with this ticket.

[Problem]
invisible information of created message on past has bewen left on browser.
It will be used on next time.

User can't aware of the left information. so, User will send unwilling message to unexpected user.
it will cause to leak information or privacy or something like that to other users.

We think this is important issue.

[how to reproduce]
1. Access to accesibilty view
2. create a message with filling all field (e.g. subject, to, cc)
3. send email
4. create a message again
5. Then, the information of message created at step 2. So, you can send email at the momemnt. then, you can't see any rcpt on to field, but information has been left. the message will be sent to previous rcpt.

Accessibility View can't handle any SMTP error.
When SMTP server returns SMTP error, no error is displayed on Accessibility View .
To make matters worse, the email is copied into sent directory. So, user misunderstands that email was sent correctly. But, email was rejected actually.
This will make users misunderstanding that email lost.

how to reproduce

1. configure smtp server to return smtp error and to reject email.
2. Send email via Accessibility view
3. check "sent" directory. there is the rejected email.

Attempting to update a user password in webadmin returns a 500 error with no error message shown to the admin.
Password doesn't update in the database.

If account's admin user is OVER quota, 'Login As User" fails from webadmin.

Once put into debug mode, we can obtain the error thrown:
