[bt-devel] search dialog improvments

[Nikolay Igotti]

 Today I implemented and commited to CVS search button in the toolbar.
Seems to work fine for me. 
Soon gonna implement some more toolbar buttons:
 "back", "forward" - go to previous/next chapter or book, as small spin
 controls aren't comfortable enogh.
 Improve search dialog by doing following:
- make results window bigger
- make links work (so you could jump to proper place by clicking on verse 
  number)
- add "copy reference" button or popup menu in search results, so 
  reference could be copied to clipboard 

 If you have any objections/comments/improvments - always welcome.

  Nikolay.
