[Licenses] Update copyright year to 2017

[VWoeltjen]

Fixes #1517

Used find <dir> -type f -exec sed -i "" s/"Open MCT, Copyright (c) 2014-2016"/"Open MCT, Copyright (c) 2014-2017"/g {} \; for each relevant directory, and a similar sed at the top-level. This had the unintended side effect of introducing trailing newlines in all files, but that just makes our code style more consistent, so I'm thinking that's okay.

Looks good to me. Review method:

1. Diff commits, and produce file with just line changes

   git diff -U0 185567c^1 185567c | grep '^[+-]' | grep -Ev '^(--- a/|\+\+\+ b/)' > diff.csv
   

2. Escape all lines with quotes for handling in Excel

   awk '{ print "\""$0"\""}' diff.csv > diff.quotes.csv
   

3. Opened diff.quotes.csv in Excel. Used "Remove duplicates" feature to produce list of unique changes which was then reviewed.

4. Reviewed 0cbbeef by hand
