Options

Accessors generation is now performed in StandardProperty, AcquiredProperty, 

CategoryProperty and DynamicCategoryProperty rather than setDefaultProperties
from Utils.

erp5.accessor_holder has also been split up into two additional modules, namely 
erp5.accessor_holder.property_sheet, containing accessor holders for ZODB 
Property Sheets, and erp5.accessor_holder.portal_type, containing accessor 
holders specific to the Portal Types (only being used by PreferenceTool and egov 
for now). erp5.accessor_holder only contains accessor holders common to both 
Portal Types and Property Sheets (such as BaseAccessorHolder).

This commit also enables code committed in r43886.

Saves in a dictionary all parameters required to create an accessor
The goal here is to minimize memory occupation. We have found the following:
- the size of a tuple with simple types and the size
of None are the same (a pointer)
- the size of a pointer to a class is the same as the
size of None
- the python caching system for tuples is efficient for tuples
which contain simple types (string, int, etc.) but innefficient
for tuples which contain a pointer
- as a result, it is better to create separate dicts if
values contain pointers and single dict if value is
a tuple of simple types
Parameters:
id -- The id the accessor (ex. getFirstName)
key -- The id of the property (ex. first_name) or the id of the
method for Alias accessors
