"new so_sql2 class: adding magic __get() and __set() methods, to be able to work more object oriented with so_sql (just a first step)

Browse Source 
you can now use $so_sql_obj->my_col = 15 instead of $so_sql_obj->data['my_col']=15; (be aware, that does NOT work with var-parameters of functions and probably references)
$so_sql_obj->id alwas references the auto-id, independent of it's name (id is a bad choice of a column-name, because it's a reserved word in some dbms)"
