Fix jquery error when using '??' in a pkey
    
    If '??' is used in a adder dialog as a pkey it can cause "jQuery15208158273949015573_1346241267446 was not called" error.
    
    Update of jquery library fixes the issue. Update unreveals an incorrect handler definition issue in ssh_key_widget, which is also fixed.
