Wiki dump improvements

[GoogleCodeExporter]

1. Searching for wiki pages, that are in the dump, does not seem to work.

2. For some pages only a redirect page is found. E.g. when you enter 
http://en.wikipedia.org/wiki/Germany it finds "GerMany" which only redirects to 
"Germany", but "Germany" itself is not found.

3. The html for the dump pages is awful. There is no formatting and code pieces 
that clearly shouldn't be, are visible. MzReader (builds upon BzReader) could 
be an option.
