Development version player name bug

The development version had two bugs in the handling of players
names/results.

One was largely cosmetic resulting in an incorrect "result"
string being displayed when the game was over, but could be
confusing.

The other was the use of "computerplays" instead of "computer"
in PGNSaveGame, so some saved games (probably mostly nextgnu
from FICS) may have the White and Black tags switched.

The result string from FICS has always been right, so anything
like "FICShandle lost on time", "FICShandle checkmated" is
trustworthy, but the player tags and results strings with
"computer wins as white" are slightly suspect.

  Simon, prototyping how getopt_long will work.

PS:

This little 5 minute game on FICS caught my eye as I was testing.

A neat little combination, I think why I like it is that White's
play, whilst not strong seems very natural. I haven't analyzed
it yet, and probably won't -- I usually ignore the wins, and
concentrate on the losses.
