data: revised indexing

* increased performance. coati is now 1.55 times as fast as at version 0.4
* integrated sourceweb parsing code
* removed astbodyvisitor
* NameHierarchy now store signatures in a new format
* storage does not allow to re-set the type of a node, once it is marked as "defined".
* made onTemplateRecordSpecParsed just create the edge, not the node.
* removed distinction between template specialitzations for functions and classes
