reading crawl dir from nutch-default.xml

Hi

i think this patch will make it way easier to configure
nutch, crawl dir
will be read from
nutch-default.xml instead of a relative path from where it
has been executed
So nutch-default.xml will have its
<property>
  <name>searcher.dir</name>
  <value>PATH_TO_CRAWL_DIR</value>
  <description>
and this value will be used instead

     Configuration conf = NutchConfiguration.create();
     conf.addDefaultResource("crawl-tool.xml");
+   
conf.addDefaultResource("nutch-default.xml");
     JobConf job = new NutchJob(conf);

     Path rootUrlDir = null;
-    Path dir = new Path("crawl-" + getDate());
+    String path2crawlDir =
conf.get("searcher.dir");
+    Path dir = new Path(path2crawlDir);
     int threads =
job.getInt("fetcher.threads.fetch", 10);
     int depth = 5;
     int topN = Integer.MAX_VALUE;


and this patch will make the CrawlDbReader find that crawl
directory
