edit/delete Comment bugs

[yytcheng]

apparently, you can edit/delete any comment regardless owner's right by changing cid parameter. See below
http://localhost:8124/editComments?cid=87&iid=5
http://localhost:8124/deleteComments?cid=87&iid=5

also, if you enter a cid that doesn't exist, the server will crash.
