[DAS2] New affymetrix das/2 development server

[Helt,Gregg]

I checked in a new version of the Affymetrix DAS/2 server this evening
that supports XML responses based on the latest DAS/2 spec, version 300.
For sample sources, segments, types, and features responses it passes
the Dasypus validator tests.  The validator was _very_ useful for
bringing the server up to the current spec!  Steve rolled the new
version out on our public test server, the root sources query URL is
http://205.217.46.81:9091/das2/genome/sequence.  In the latest version
of IGB checked into CVS, this server can be accessed as "Affy-temp" in
the list of DAS/2 servers.

Although the server's XML responses conform to spec v.300, the query
strings it recognizes still only conform to a subset of spec v.200.  I
expect to have the queries upgraded to v.300 tonight.  But it will
probably still only support a subset of the query filters: one type
(required), one overlaps (required), one inside (optional).

This server also supports bed, psl, and some binary formats as
alternative content formats, depending on the type of the annotations.
