Add NeedsManualRebaseline suppressions for vs2013 switchover

This change suppresses the remaining failures resulting from the
switch to Visual Studio 2013 until scottmg or I can go through
and rebaseline them. There's probably a couple local failures from
my machine that shouldn't be rebaselined, and a couple of legit bugs
as well, which is why I don't want to use 'NeedsRebaseline' for the
bot to automatically deal with this.
