[RC1] When comparing shields, Block value colors are wrong

[LNQ]

Minor thing, but this got me confused when I first started playing ToME a month ago. When you press ctrl to compare your equipped shield with a new one, the coloring of the Block value is wrong: if the new shield has a higher block value (which obviously is better), the change in block value is displayed in red, as if it were worse. Red = worse is consistent in all other comparisons, so as a newbie I had to look into it to make sure that a bigger block value isn't worse.

Likewise, if the new shield has a smaller block value than the one equipped, the new block value is shown as green as if it were an improvement.
