#2387

• Adapted behavior of the matching in the TypeSelector that it behave the same as the NewItemDialog. The search string is tokenized by space and matches if all tokens are contained, (eg. "Sym Reg" matches "SymbolicRegression...").
• Enabled navigation with up- and down-arrow in the tree while the search-box is focused.
• Improved response time of NewItemDialog and TypeSelector when they contain a large amount of nodes.
