JIRA ticket: LIMS-1962

Summary:

The Download button sometimes opens attachments in the current tab, we should allow explicit downloading or opening.

Changes:

• Add an 'Open' button to log files, which opens the file in the browser tab
• Make the 'Download' button always download the file
• Display .lst files as plain text

To test:

• Go to any data collection with auto processing results, then open the Auto Processing bar
• Click the Logs & Files dialog. Checkl each file of type "Log" has 3 buttons
• Check the Download button downloads the file to your hard disk, that the Open button opens the file in the browser tab, and the View button opens it in a frame
• Zip one of the files, keeping but renaming the original (to preserve permissions), and check it behaves the same, then undo the renaming after, eg

gzip -k xia2.html
mv xia2.html xia2.original
# test Synchweb still works as expected
mv xia2.original xia2.html
rm xia2.html.gz

• Find a Fast EP ersult, check you can do Open on a .lst file
