show mediainfo export within mediaconch gui

[dericed]

In the latest release, when opening the MediaInfo view there's a Download Mediainfo report option with a dropdown to show export options. Then those exports can be saved to a file. I propose an option to 'view' the export without having to download it, so the PBCore, FIMS, ebucore, etc could be flipped through and reviewed without having to create a download file.
