Add marker on targets description for track/telepathy

[wobbly]

When using track I often have trouble telling when a target comes in to actual los. Something to distinguish the difference between los & detection would be handy.

I had a similar problem as archer using Mercul's Second Eye. turns out there is such a thing as too much information, especially since using keyboard shoot autotargets enemies seen by the eye but not in LOS.

I've found this to be somewhat confusing at times as well.

Another somewhat related issue is that it can be difficult to tell terrain revealed by vision or similar and terrain that's been explored in person and is monster-free (probably).

And talents set to "auto-use when no enemies are in sight" ignore monsters seen via track/arcane eye - which is ok when they are behind a wall, but problematic if they are just hidden in darkness. Might be better if they did count as seen, because that's only an annoyance, but loosing a turn in the wrong circumstances can be fatal.
