#67 Add java support in xcscope

[anson zhang]

This patch just add java support in xcscope, add java files to the indexer, and add ignore .svn files, since svn will have lot of text.

Add this because java language was very popular, and these was a lot of java code. Also cscope support java very well. I think this will make cscope better.

I've tested this patch for years, When I going to a new linux, I always need to change the cscope-indexer like this patch,could you merge this patch in upcoming cscope release?

This patch doing two ting:
1. add .java file to indexer files.
2. ignore .SVN file that will product many garbage.

Thanks.
