Search results for current view and full graph

[bestchai]

Right now, the existing searches apply to the current view (with its layered transformations, such as hidden hosts and collapsed nodes) so that there may be more matching events in the full graph (ie. when no hosts are hidden, no nodes are collapsed). It would be helpful to have a count of how many instances of the search term was actually found in the full graph versus showing that no instances were found even if they are just currently not in view.
