[pca] Patch download fails

[Martin Paul]

Thanks Jan for the detailed analysis, that makes perfect sense!

I have made two changes to the development version of PCA:

   http://www.par.univie.ac.at/solaris/pca/develop/pca

   - Add the GeoTrust CA cert
   - Use --no-check-certificate with wget versions <= 1.12

The bug with recognizing alternative names in certs seems to be fixed in 
wget 1.13.1 onwards.

For wget versions <= 1.12 I have no choice but turning off certificate 
checks. That's ugly, but if Oracle doesn't change the certificate, there 
is no other choice.

Can somebody please check whether the latest wget patches for Solaris 
(125215-05 and 125216-05) provide a version of wget newer than 1.12, and 
if so, whether patch downloads work with the current development version 
of PCA?

I'd also like to encourage anybody to test the new version with other 
versions of wget, and see whether it works in all environments. If patch 
downloads fail, please post output of "pca --debug -d 151615-01".

Best,
Martin.
