[LogiLogi-list] Page-editing & creation in place & db-reload

I added page-editing and page-creation. So from now on it is possible
to edit, and create new pages, see the demo at:
http://www.logilogi.org:3000/

(though, don't add anything important to pages yet, as the development-
db will be re-created on each update).

The layout is still the old one, and the Edit/View/etc. links above
and below the articles are still messy. I will improve that if Bruno
has integrated his marvellous work on the layout (or told me that he'd 
rather have me to integrate it ;-)

Also I made some minor changes to the db-scheme, before you encounter
errors, please run rake redo_dev_db.

Also note that there is one strange error I get that seems ruby-
related, as the logi_version_test fails on some Ruby prettyprint file
if run together with all tests, while it succeeds if ran on it's own.
I get it on two different machines. If anyone has an idea ?

I'll be away for the weekend again. But I'll be back on monday.

PS: note that our server is moved to a different rack by our 
colocator somewhere in the coming days, so some down-time is 
expected...
