Improve Committee-aggregated Feedback Pages GH2954/2955
(1) Add a "More Info" or make it so that clicking on the "comment" in feedback takes the user to the "All" feedback page for the activity, course, event, or lodge stay from which that feedback originated.
(2) Add a "Download All | Download Selected" button to the bottom of the page that downloads a spreadsheet file with one sheet/tab for each feedback survey (e.g. Course Feedback, Field Trip, Lecture, Seminar, and Clinic Feedback, Trip Feedback, etc.). Each sheet will have meta data (e.g. title, dates) from the activity, course, event or lodge stay and then the feedback responses in the columns.
