add total file count on first page

[Peter Johansson]

Since it is trivial one could add total number of files. Perhaps also for each individual author (?)

For each author? Do you mean number of files contributed to or added? Maybe both?

I don't know what I meant but I can come up with the following counts:

1. Files ever touched (seen in the log)
2. Files ever contributed (StatsAdd > 0)
3. Files contributed to current content (ClassicStats > 0)
4. Files added (oldest log entry for file)

Since first page is based on ClassicStats I think #3 makes most sense.

Implementation wise I think this could be done using the visitor pattern.

(In [1254]) closes #228. Added count number of files and directories on first page. No count for individual authors.
