documentation improvements

dont forget to give dolibarr user permissions needed by doliwoo (dolibarr webservice permission checks is not done everywhere - ie order creation or update does not check permissions, so you can easyly forget to set them but you will have a problem later when doliwoo try to do a fetch of the order, because the permissions are checked at this moment ! (reported on dolibarr dev mailing list)

This is already documented in the french user manual (Check the wiki).
With #65 fixed, I guess this ground will be covered.

Feel free to comment so I can reopen the bug if you think this is not enough.
