orbiter 9628db6cdc enhanced memory allocation during database access:
- refactoring of kelondroRecords; this class is now divided into
  kelondroAbstractRecords, kelondroRecords, kelondroCachedRecords, kelondroHandle and kelondroNode
- better abstraction of kelondroNodes, such nodes may now be crated by different classes
- a new Node defining class kelondroEcoRecords defines Nodes that do not need so much allocation and System.arraycopy
- there is less memory transfer on the bus, especially for collection index
- now half of memory needed for web index access
