[Seaside] STTutodoApp

[Norbert Hartl]

Hi,

I tried the Magma SeasideHelper Todo List Tutorial at
http://wiki.squeak.org/squeak/6021. I found two things
missing:

- In order to use the App some has to install Scriptaculous
  and Cryptography (maybe should be added to the squeak
  page)

- The example does not work for me. The 

StMagmaCollectionDatabase class>>modelKey

contains a missing class. Removing the whole selector 
made it work for me.
