[Building Sakai] change config values on the fly

[Charles Hedrick]

Matthew gave me the answer.

I agree that persisting things in the database has advantages. It would let us build a tool, so I could change things once instead of having to go change them on each front end. But Matthew’s version of my original hack did let me solve the problem.

YMMV on this for sure, but this worked for me and should get you a little further at least. There was work in more recent versions of Sakai to make so properties could be registered so maybe some day there'd be a UI that could change it like how the message bundles can be changed live. But in any case it makes it a little different for changing them now.
