[DAS2] xml namespace uri

[Andrew Dalke]

Please use

   "http://biodas.org/documents/das2"

for the XML element namespace.

The two current servers (Allen's and Steve's) use

   "http://www.biodas.org/ns/das/2.00"

which is wrong according to the spec, for the last 2 years it's been

   "http://www.biodas.org/ns/das/genome/2.00"

Since the servers need to change anyway, might as well make it
something a bit more readable, and shorter.  :)

I've checked all the current dasypus (validator) software into
CVS, btw, and updated all of the example xml (draft3/ucla/) to
use the new namespace.
