[Zope3-dev] Merge experimental-zwiki branch to trunk

[Baiju M]

Hi,
     I would like merge `baijum-experimental-zwiki` to zwiki trunk.
http://svn.zope.org/zwiki/branches/baijum-experimental-zwiki/

The major changes are:
 1) Added buildout support
 2) Moved code to `src` folder
 3) Use a test layer for functional testing

Any comments ?

Regards,
Baiju M
