Last Changes:

07/27/06 (honzam)
 - moved from CVS to SVN (Subversion)
 - "Modify Content" group operation in Item Manager is improved. It uses
   new AA_Transformation API, so new transformation function could be
   easily added. There is new "Translate" transformation, by which you
   are able to transform one value to one or more values. It works also
   with multivalues. It uses new TabWidgetToggle for parameter setting.
 - New possibility to change URL of uploaded files/images (per slice
   basis). Images was stored with general AA URL for all slices, which
   is not always what you want. Now you can redefine it on slice setting
   page. Not 100% finished, yet.
 - Session IDs are propageted via cookies (if possible - if not, URL
   parameter used - just as before)
 - AA_Slices and AA_Views classes used for slice/view properties,
   where possible. Those classes caches slice/view properties, so it
   reduces number of database calls.
 - Started work on AA_Components class used for plugable classes.
 - Started work on TabWidgetToggle - Widget, which allows you to set
   different parameters for different options in the selectbox above.
   Say you want to inport data from CSV or XML - for both formats
   you have to set another parameters, so you first select the CSV
   and the parameters like "delimiter" apears on the screen
 - Started work on AJAX editing - Proof of Concept - you can use it like
     {ajax:{_#ITEM_ID_}:headline........[:_#HOW2SHOW]}
   which means, that _#HOW2SHOW for _#ITEM_ID_ will be printed inside
   the div and after click on it the textfield for headline........
   is displayed and the field could be directly edited. It works
   in AA Item Manager as well as on public page - you just need
   to attach javascript/ajax.js to your page. It is just experimental
   version, yet.
 - Started work on AA_ChangesMonitor class which will track the field
   changes/history - we are still at the beginning, here.
 - New class AA_Fields holding information the field information
 - New AA_Metabase class which will be used to hold all the informations
   about table structure. It will be additional database abstraction
   layer.
 - New AA_Condition class for conds[] handling
 - aainputfield renamed to AA_Inputfield
   (used new naming convention for AA classes).
 - views class renamed and AA_Views. AA_Views was improved to use static
   class variable to cache the view properties which reduces the number
   of database queries. Static class variable also allows us not to use
   global variables for that cache.
 - grabber class renamed to AA_Grabber, saver class to AA_Saver
   and moved to grabber.class.php3 file
