#427 'Open Original File' at QA step opens file from the input media in read\write mode

[Kirti Chennareddy]

Testing on DPR 5.1.2 Java6testing , Java7 branch

At QA step in preservation, when user clicks on 'Open Original file' file is opened from the qf_data folder on the input media in RW mode. This allows user to modify and save the file on the media. As a result when you reprocess the transfer job into PF using the same input files, you will get a checksum error.

DPR should open the file in read only mode or in a tmp location to avoid any accidental modifications to the input file.
