[FIX] api: avoid to return all fields *2many in onchanges

When an onchange returns a change in a 2many field line (a '1' tuple, update), avoid to return all fields of the *2many field but only the altered field.

Otherwise, the web client regard all the fields of the 2many as dirty, and try to write on all fields (even if the value is the same, thus)

[FIX] fix autocompletion problems with quick presses

Problem was that when the user types quickly in the search bar and press
enter, the keydown event of the enter key happens before the keypress
event of the last key entered.  This means that the autocompletion has
a wrong string.  The fix is to move the enter selection detection from
keydown to keyup.
