[forms] take a look at inlined form to guess whether the form requires multipart or not

[form] simply skip unknown argument given to form constructor, don't fail

fix argument given to changestate form selection

can't use anymore make_uid to generate a valid js var name

remove debug raise

merge

statuschange form view only works w/ one entity, fix selector accordingly

fix sort of fields vocabulary: should consider option groups

[widgets] change make_uid() seed to make slider ids xhtml-valid

introduced to ease overriding for fancy stuff...

cleaner code

don't propose inlined form if user can't edit the entity

cleanup, smarter sort control to avoid it when not necessary

facets enhancement: can now set label_vid to use a view instead of a simple attribute as label

fix/enhance i18n context usage for inlined forms

don't show label if no label given
