[Patch] New performance test for MapCSSStyleSource#apply and for OsmPrimitive#get/put/getKeys

[michael2402]

Some tests that test the performance of those methods. I use those to tweak the MapCSS performance a bit.

Patch 0004 is optional. You can add if if you think that the test is running too long.

Thanks, very interesting results!

Why are [key] rules slower to apply than [key=value] rules?
