[FIX] better responsibilities on objects POS
[FIX] recursion
[FIX] difference POS / Cash
[IMP] readable code
[FIX] web: fixed css of hidden input file: a hidden element could interfere with other elements
in the dom, leading to some fields not being accessible.
[FIX] ir_actions: server action: check the validity of write_expresison only if defined. Also check for the related model only if set in the onchange.
[FIX] ir_actions: server action: when creating or writing value on a record
through a server action, try to correctly set the value to write on a given
fields according to its type. For example many2one fields should receive an
int, not a unique containing the id of the new value.
[IMP] Graph views: show always measure + filters record measures in context
[IMP] board: do not filter actions anymore

Starting from v8.0, there's only "My Dashboard". We can assume that we
have access rights to all the actions we pin to our proper dashboard, so
we can remove this filtering. Furthermore, this was a large performance
pitfall.
