Allow users to delete an adoptable

[tahbikat]

Getting errors. I tried adding this to the doReleasePet in the class_ownedadoptable.php and got a fatal error.

Fatal error: Call to a member function delete() on null in /home/mysgardia/public_html/classes/class_ownedadoptable.php on line 103

Moved it to the function in myadopts.php and it displayed this error on page:

Database error 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 'Lavie'' at line 1

EDIT: I changed it to this to do some experimenting (after backing up db lol) and it said I successfully released the pet yet I still have it. :<

$mysidia->db->delete("owned_adoptables", "aid='{$this->aid}'");
