Improve the target stats display on the in-flight map

[Henrik Heimbuerger]

1. "type/speed/range" should be capitalized consistently with the rest of the UI -- either make everything lowercase, like the personal stats on the left of the map or capitalize these correctly.
2. "range" should be renamed to "distance", as it is always relative to you.
3. The distance should be postfixed with 'm' like all other distances.
