Warning when updating to version 4.0.4

[mckillo]

Joomla displays a warning message when Attachments is updated, because the pkg_attachments.xml file haven't the hashs of file (sha256, sha384,sha512).

For the latest version, the attachments-4.0.4.zip file has the following hashes:

7EBB9C1297E7F20610689E31669D8976940F600ADF72034EA993566A062B1777 02812D2B49EC23DFB19F24F780082B6C4421756232B5624C006A19EAA8A369677C38EBAF11CFB46CB93188E93A4C582E B4878B03D44E151ACCBBAB15D1100F8AEB070F82B21E851081078D0A33D3CBC4DA126397AD7EE1AA229317C6C617001DA53526D64F54F2E1F15D3126BE51EB82

These hashes must add to pkg_attachments.xml file.
