[MERGE] Added search_read() in ORM.py for new server-side web framework
[REF] fields: removed deprecated view_load attribute and removed useless first argument in property fields definition
[REF] ir_property: changed 'value_reference' and 'res_id' fields into char instead of reference fields because the code was fuzzy, the performances very bad (at least since 'view_load' attribute has been removed), and because there were no reason to have them as references (even from an useability point of view)
[IMP] ir_property fields: added the possibility to use 'selection' field type as properties
[FIX] ir_property: fixes in property fields related to multi company use cases
