[Bug-gnubg] Some small problems with recents UI changes

[Philippe Michel]

I have found that some of the recent changes in the UI are annoying. In 
some cases, it may be more a matter of taste than a bug though :


The arrow showing who's on roll can be hard to see. For instance I 
use the Red/Blue design and the black arrow is almost invisible. Maybe 
there could be a 1-pixel white border around darker arrows and a black one 
around lighter ones, or someting like that.

The cube is oriented towards the player holding it or sideways initially. 
Like in real play maybe, but please consider that there is only one person 
looking at it, and it is from the bottom of the screen.

In the match statistics panel, there is a MWC value for the Snowie error 
rate that is always 0.

In the Analyse menu, the backslash in "Match\session" looks weird. In 
similar cases elsewhere, a forward slash is used.

In the same menu, match and session are sometimes merged, sometimes not 
(like in Clear analysis).

In plain text exports, the statistics part is padded with spaces at the 
end of those lines that are not already too long. This part now looks 
awful in a standard 80 columns window.
