Move the whitelist to the database to the App Engine Datastore.

Move the WhiteList to the datastore from a white deployed with the App
Engine Instance. This includes adding access to the App Engine standard
remote access api (also implemented in the "manhole" app) which will
be used by the whitelist update script. The sample whitelist, used
for when the white list was part of the deployment, has been removed.

Added Slider visible component. A Slider is like a ProgressBar that adds
a draggable thumb. You can touch the thumb and drag left or right to set the
current slider position. This triggers PositionChanged, reporting current
position of the slider thumb.
The slider has min, max and initialPosition properties.
The reported thumb position can be used to dynamically change another
component property; such as TextBox font size or Ball radius.
