[Avida-cvs] multi-threaded viewer

[Kaben]

Hi.

I'm about to commit a threaded version of the Qt viewer; it will only
compile with a version of Qt configured for threading.  The rest of avida
will still build, including the ncurses viewer.

***

I configured threading Qt 3.0.1 using
	configure -no-g++-exceptions -thread

For simplicity, some gui events cause immediate access to population data.  
For example, zooming-in on the map causes cells to be redrawn in the
middle of an update using the current states of organisms, rather than
their states as of the end of the last update.  Claus and I discussed this
issue, and decided it isn't a problem.
