[FIX] web: properly transfer field properties

Before this commit, the field properties (attrs, fieldNames, fields)
were not correctly given to sub views in many case

expected:
* use widget many2many on one2many field
* create record when click on save in formDialog
* do not send create command to the server
* use the fields defined in the field node (instead of tree view fields)
* use the fieldNames instead of the record to get field values
