zope.app.twisted is configured to be used with BlueBream, so it can be removed
from dependencies.

For those who are not aware how to remove a dependency, here is more
detailed steps:
1. Open the setup.py and locate install_requires keyword argument.
    The keyword argument will be a list of dependencies.
2. To remove a particular dependency, comment that line or delete it.
    The 'zope.app.twisted' must be the second dependency listed there in BB 1.0
3. Run buildout again

BTW, I am preparing a Blueprint for 1.1 release (Draft):
http://wiki.zope.org/bluebream/RemovalOfDeprecatedPackagesIn11Release
When I am done with that draft, I will send a mail for discussion here.
