[effects] Use standard arrow cursor in Present Windows & Desktop Grid
requested to merge ngraham/kwin:use-arrow-cursor-for-present-windows-and-desktop-grid-effect into master
The pointing finger cursor is used to show that a piece of text is a clickable link, and it is inappropriate to use it in other contexts. Regular UI elements that do something when single-clicked continue to use the standard arrow cursor in other contexts, so let's follow that convention in the Present Windows and Desktop Grid effects too.
