Plone.formwidget.querystring

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

- If we set background to 'white' we should set foreground to 'black' to avoid
people getting white font on white background if they use white font color
for their plone sites. [saily]

- Add handling of the RelativeDateWidget, already expected to exist in
p.a.querystring.
[tmog]

- Add jquery dateinput to dateWidget and dateRangeWidget.

- The widget can now be hidden, when clicking on the
window or the widget. The event is only effective
when the widget is displayed.

- Translations are now in Plone domain
[bosim]

- Made the widget a bit more resistent to missing entries, i.e. vocabularies
or in other way indexes. The problem occur if an option is deleted from the
registry but not deleted from the collections in before hand.

- Update import path for pagetemplate. Now only works with 4.1 and higher
[do3cc]

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

- Fix sort-reversed checkbox javascript.
[timo]

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

- Stop hardcoding the field name so it works with other field names and
prefixes.
[davisagli]

- Rename ArcheTypesQueryWidget to Querywidget to avoid confusion.
[timo]
