increase display time for styles and presets tool tip

[Klumbumbus]

What steps will reproduce the problem?

1. preferences
2. projection
3. map paint styles or presets
4. hover on a style/preset to show the tool tip
5. There is a lot of text (additionally some have long descriptions) and the time until the tooltip disappears is to short to read it all
6. when you hover again it takes some time until you find the place where you stopped reading and when you finally found it the tooltip already disappears again
