Cleaned up some UI issues on the StudyPage, in the CSS and StudyFilesFragment, with some text being too light of a gray color, and not contrasted enough with the background. Also, fixed the alignment of the new "(Request Access)" link, that was sized too large and misaligned with the "Restricted" label and icon, because it was missing a style class. [ref 3182]
