Change the value of the delay for the autocomplete widget

[Stephane Wirtel (OpenERP)]

Currently if you have many records with the same prefix for the name and you want to do a search for this value, the autocomplete widget starts the JSON request just after the first keystroke. The problem, the server will load all the records from the database and the server risks to be very slow.

Example: 1000500

After the first keystroke, the client will start the search for the "1000" and not for "1000500".

Just add a setting for the delay.

To fix in trunk and stable-7.0. Thanks
