agrovocfield 6.x-3.0

Code refactoring done.

• New funcionalities were tested for PHP 5.3.x
• New approach based on OOP for remote or local retrieving of Agrovoc terms
• Importants functions were shifted and renamed from agrovocfield_autocomplete.module to agrovocfield.module to allow writing new widgets more easily
• 2 widgets were added: agrovocfield_text and agrovocfield_automatic
• agrovocfield_text widget is only a textfield but allow reuse clearly parts of its code for other widgets
• agrovocfield_automatic widget allows automatic indexing for body field OR filefield (provided by filefield module) OR upload file(provided by upload core module)
• For local searches, you need to store all terms of Agrovoc in your database. First, you need to download a file from http://cambio.name/agrovocterm.csv.zip and put (after uncompress it) inside folder named sites/all/modules/agrovocfield/bd/. Next, execute update.php for loading data. This is mandatory if you want to setup local searches
