Added markup to data file listing on data package page

Haven't been able to move this section
Merge branch 'dryad-staging' into dan-data-package-page
Add original common.xsl from dri2xhtml-alt/aspect/artifactbrowser/
Disable apply-templates that generates the file listing
Implemented file listing

Files in a data package are based on a dri:referenceSet.
The template that renders the data package page is operating with the package's METS document, but the referenceSet is contained in the DRI document
So this change reads in the DRI document to render the file listing in the desired location
Set width of data file table on package view to 100%
Tweaks to file listing markup
Fix View File Details links in file listing
Merge branch 'dryad-staging' into dan-data-package-page
Merge remote-tracking branch 'origin/dan-data-package-page' into dryad-staging
