On goto, show marks with delay in *evil-marks* buffer

This commit adds functionality to the previous commit (i.e.
mark-goto-buffer-not-line), and shows marks in the *evil-marks* window after a
delay (similiar to which-key). It is especially handy to remind of which mark is
associated with which buffer.
