Publishing ZMI CSS/JS-Resources

[drfho]

Added a ZCML snippet to ZMS-configure.zcml for publishing ZMI CSS/JS-resources.

Since zopefoundation/Zope#1166 general GUI resources are not public anymore but limited to the ViewManagementScreensPermission. If using bootstrap.css or fontawesome for the website-design, these resources can get accessed by changing its permisson by adding the path to a overrides.zcml for ZMS:

<browser:resourceDirectory
      name="zmi"
      directory="~/virtualenv_demo/src/zope/src/zmi/styles/resources"
      permission="zope.Public" />

overrides.zip

The directory-directive has to be adopted to the local installation path (this is not convenient!).

A late Zope-PR zopefoundation/Zope#1204 may have removed the permission to any non-manage-user; thus the upper enhancement is not only needed for 3rd-view but for ZMSEditor etc. accessing ZMS-ZMI.
Actually this is a litle bit too complicated; any other ideas?
I doubt that adding the ViewManagementScreen-permission to the ZMS*-roles (except Subscriber) is a good solution, because the user should work in ZMS-ZMI and not Zope-ZMI.

Now, the permission "View management screens" is added to the basic ZMSRoles for getting access to Zope-ZMI-Assets implicitly.

IMPORTANT: this only works if a new ZMS-objects is added into th Zope-object-tree. For existing ZMS-instances the new permission has to be added manually with ./manage_access:
