Added Fall 2015 Seminar Files

[fcjou]

• Added all the Fall 2015 Seminar Files (for all seminars whose
  information has already been populated)
• Changed the 'name' field to handle multiple entries
• Added a 'location' field

Note that the build test failed here. I had the same issue with my initial copy/paste of some text.

You can see the error by following the details link:

The problem is a smart quote somewhere in a file.

The smart quotes are fixed, and I also updated/added the name and date fields.

Since the second commit was a "fix", not distinct content, "style" says you squash it:

git checkout master
git pull
git push

git checkout calendar-files
git rebase -i master
git push -f

[fcjou]

Done!
