1.3 release and SOLR-646

[Ryan McKinley <ry...@gmail.com>]

I'm leaving for vacation tomorrow and will have little or no internet  
access until sept 1 -- from the 1st to the 7th, I will have limited  
access.  The one remaining issue that I am concerned about for 1.3 is  
how to set the "dataDir" for various cores in a multicore environment  
-- SOLR-646 aims to solve this issue.

For more background:

The original "multicore" patch included a dataDir="path" attribute in  
the multicore.xml file.  Hoss found this problematic since there would  
be multiple places to set the dataDir -- it is already set in  
solrconfig.xml -- after some discussion, we agreed a good approach  
would be to let you set system properties that are valid within the  
scope of each core from the multicore.xml (now solr.xml) file.

If SOLR-646 proves to be too complicated to get into 1.3, I would  
suggest adding the dataDir  attribute back to the core specification  
and adding documentation explaining the potential pitfalls.
