Changed the way the autocomplete panel is opened : as soon as a search is started to show a spinning wheel to show user that "something is happening".
Added image of spinning wheel, used while searching.
Added a timeout for searches.
Added preference to handle search timeout.
Added a search counter ('searchID') that allows to filter obsoletes returns from remote searches.
Changed prefs widget : min & max for timeout.
Handling of warnings ; and storage of addressbook's name while searching.
Handling of special case : when ldap searches return some results after the autocomplete is shown/a timout : it may re-compute the autocomplete while displaying it with only the last results.
So at the end of search (normal/timeout) we have to make any remaining search obsolete.
Comment cleaning : removing all 'numRemotes'.
Comment ofdebug logs.
Use _logError() for real error logging.
Changed method to modify text in pref overlay.
