[jsword-devel] Install bug fix

[DM Smith]

I noticed that I almost always got an exception when installing a book. 
The more books I had installed, the more likely it was to occur.
Anyway I found and fixed the problem. The problem was that the wrong 
"fire" was sent. It was doing fireIntervalAdded(0, last)
when it should have done fireIntervalChanged(0, last) or 
fireIntervalAdded(x, x) where x was the position of the single item added.

I also made the list of dictionaries and commentaries to be 6 instead of 4.

I also found a problem in the build and in findbugs as they were using 
lucene 1.3 and not 1.4. I fixed that as well.

I have also checked in all the other changes I had mentioned before.
