Merge branch 'ohmage-2.16' of github.com:ohmage/server
Fixed a bug and updated the character encoding.

There was a bug when reporting whether or not invalid points were being retained. The response from a survey/upload call will now correctly echo back whether or not points were saved.

In an attempt to fix some character enconding issues, the stream data is now being stored in UTF-16 format, instead of UTF-8.

References #612
Fixed a bug regarding users reading their own data.

Users could not read their own personal information if they did not meet one of the criteria for reading other user's information. This has been fixed.
