Collective.z3cform.select2

----------------

- Remove specific css rules that was introduced in 1.2
[vincentfretin]

- Fix widget in overlays. If you upgrade from 1.1, you need to reinstall
the profile to add a css in portal_css.

- Wrap call to select2 initialization in JS function `initializeSelect2Widgets`
so it is easy to call from everywhere (like in an overlay initialization).
Parameter width can be specified when calling `initializeSelect2Widgets`
and defaults to `resolve`.
