[Chandler-dev] chandlerdb updated (0.6-37)

[Andi Vajda]

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

This update inserts an 'op' argument into the afterChange method protocol.
op can take one of two values:
   - 'set', meaning the value was set or changed
   - 'remove', meaning the value was removed

I changed all afterChange methods I could find to take the new argument.
Yes, this includes the @schema.observer -declared ones.
