[facet] provide hasRelationFacet (backport from CMHN)

[facet] duh ? jQuery crashes on facets with only one element. Strange that this is the first time we hit this bug

[facets] add new unchecked's checkbox image

merge stable branch into default

[facet] provide a DateRangeFacet (still need to refactor, maybe create a CWWidget)

[utils] move datetime2ticks from cw.web.views.plots to cw.utils

[javascript] provide a strftime method to Date objects Rely on toLocaleFormat when it's available. If not, this just returns '%Y/%m/%d'. A nicer implementation will come later

oops...

we can now use self.req

turn every form class into appobject. They should not be instantiated manually anymore.

tests broken; module deprecated; remove tests

useful to have yes returning 0.5 by default

be stricter on catched exception, fix Time parsing

fix import

do not store req as an attribute of ApacheURLRewrite - fix test

obsolete methods

[views] change schema views: remove view eschema and use tabs for cwetype

[views] get tabs to work with startup views

merge

turn renderers into appobjects

col may be None

backport stable branch

[javascript] fix AJAX user preference validation - use $elt.val() instead of $elt.attr('value') - fix radio button handling

bugfix for plots

merge stable branch into default

set default select size to 1 into the widget

if choices is set and widget not explicitly specified, use Select in base field

basic views for python values (eg without any result set)

move widget selection's logic on fields

move view method's logic on the registry, so it's easier to call it from outside an appobject. Also make rset argument optional
