When no region is active mc/mark-next-like-this and mc/mark-previous-like-this should create a cursor one like up (or down).

Browse Source 
Added the functions mc/mark-next-lines and mc/mark-previous-lines
which create cursors one line above and below point.

Refactored common mc/mark-previous-like-this and
mc/mark-next-like-this functionality into mc/mark-more-like-this.

Changed mc/mark-next-like-this and mc/mark-more-like-this to call
mc/mark-next-lines and mc/mark-previous-lines when there is no
active region (instead of erroring).
