Update button for "Games To Play" and "Games Played" sections doesn't actually update the list

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Start the app and navigate to either "Games to Play" or "Games Played".
 The current list is correctly downloaded from BGG.
2. Add or remove a play or the "Want to Play" status from a game the
already existed in your collection on the BGG website.
3. Return to the app and navigate back to either the "Games to Play" or
"Games Played" section.
4. Press the Update/Refresh button.

What is the expected output? What do you see instead?
The "Games Played" or "Games to Play" list should be updated with the
latest changes that were made to the website; however, the app only
displays the original list that was downloaded the first time the app was
run.  The new updates can only be acquired by clearing the game cache in
the settings and redownloading the data.

What version of the product are you using? On what operating system?
BGG app version 1.7 running on an iPhone 3GS running OS version 3.1.3 (this
condition also existed in the previous version of the BGG app and perhaps
before that)

Please provide any additional information below.
Note that the update/refresh button works as expected for the "Games Owned"
and "Games on Wishlist" sections, but does not work for the "Games to Play"
or "Games Played" sections.

Whoops, I'm actually using version 1.7.2 of the app. It doesn't look like the 
in-app
version label has been updated.
