A Couple Fixed Bugs

I found a couple bugs a while ago that I understand have already been fixed:

• If there was only one tag, the app server would return a string representing the tag, rather than array of size one containing the tag. Not hard to code around, but I believe it was inconsistent with the API.
• The comments on the reference web server implementation seemed to always be from the person who submitted the picture, rather than who submitted the comments

I know this is old news, but I didn't get around to posting it before.
