REQ: Vertical lines to separate sections and Filtering

[gh658804]

It would be nice if 2 things could be added to coriolis.

1. Some vertical lines which would separate sections. They would make it much more easy to compare 2 adjacent ships. Check the image for a sample (first 2-3 lines).
2. A simple filter to display only one size of ships (S/M/L/All). Sorting by size sort-of-works, but it mixes different sizes of ships and it's not convenient for comparison.
