[Dev] chandlerdb updated (0.5-24)

[Andi Vajda]

After your next 'svn update' you need to get the latest chandlerdb version by 
running in 'chandler':
   make chandlerdb  - OR -
   make install

Most attribute aspects are now cached in a live cache shared between the 
Attribute items and Chandler the corresponding attribute descriptors installed 
on Item classes. Aspect access is between 2 and 20 times faster.
