Title: Made Products.UserAndGroupSelectionWidget and plone.dexterity optional

- Cleaned up dependencies that already ships with Plone
[alecghica]
- Made Products.UserAndGroupSelectionWidget package optional.
Products.UserAndGroupSelectionWidget will be imported only
if package version is greater then 2.0.4 as it brings dependencies
like plone.dexterity witch conflict with other packages found in
the current Plone release.
[alecghica]
- Fixed register users form to work for the case when
Products.UserAndGroupSelectionWidget is not installed/used
[alecghica]
- Added info on how to make plone.dexterity optional
