Some changes/notes

Notes:

* I really recommend using `httrack` instead of `wget` to clone websites for offline use
* The SQLite locking issue you mention won't happen. Dash opens the SQLite databases in read-only mode. The only thing that will happen is that the values in those entries will not be updated until you collapse and re-expand the docset (i.e. the count of the number of Class entries won't update).
* I don't mind you copying the `javadocset` binary and doing whatever you want with it.

Great job! :+1:
