  update `catalogView.dtml` to changed behavior for "empty searches" (#104)

* update `catalogView.dtml` to changed behavior for "empty searches"

* Fix issue reference in `CHANGES.rst`

* new method `searchAll` (similar to `getAllBrains` but as a sequence instead of an iterator); document `searchAll` and `getAllBrains` in the interface; more efficient `catalogView`
