Search engines: Point to local version of Wikipedia

Look at the locale and point at the appropriate version of Wikipedia.

Before this commit, mintmenu always pointed at the English Wikipedia.

Note: This commit might introduce regressions when a particular locale isn't supported by Wikipedia.
If this becomes a problem, we can fix this based on feedback.
