Search list should show all results

[Forestidia86]

Edit Simon: This is now github issue #429: Search dialog, implement scrollbar and up/down nav.


At the moment the search list only shows 18 of the matching results.
Imho all matching results should be shown though.

The search dialog also has a fake scrollbar! And it forgets all the indexed levels after you close it.

Yeah, the search dialog needs more work. geoo has already complained that it doesn't support selection up/down by keyboard. With level tags that we want to filter via search, the search dialog becomes even more important.
