It is no longer possible to view graphs having no edge definitions
Fixed #941. Showing a collection did send a count request, as well as a fullCount for the query. fullCount in this case is superflous and has been removed. On the way fixed an issue with the number of documents not updating while filtering.
Added a test that the graph viewer is not loaded for graphs without edge definitions
Merge branch 'devel' of github.com:triAGENS/ArangoDB into devel
Added first draft of new graph features 22
Added a specific cleanup when deleting cluster plan or midifying it
Fixed an error in a general graph example
Improve error handling in arangorestore.

In particular:
  - Notice if collections mentioned in _from and _to fields of edges
    do not exist.
  - In cluster case make the coordinator report errors from the
    DBservers better.
  - Fail more quickly if arangorestore does not go well.
