new release 1.11

[petschki]

@thet @ale-rt anybody of you willing to release 1.11 ... this would fix:

• https://github.com/plone/plone.app.widgets/issues/162
• hard dependency on z3c.releationfield
• some configuration convenience

PS: or 1.10.1 is also OK 😉

+1 for releasing the 1.x branch but I have no pypi power. CC @plone/release-team
