Use j/k in spacemacs buffer for widget motions

Currently j/k were only navigating between lines, but hitting RET
wouldn't work on a recent file and the like, when the cursor wasn't
directly over the filename. Changing j/k to widget navigation, ensures
that the cursor is always on something clickable. This change should
make the home buffer feel more at home for evil mode users.
