Most Common Surnames in the Statistics Block

[meliza]

webtrees should print the Most Common Surnames in the Statistics block using the same logic that is used in the Top Surnames block.

Now id uses a sorting field and McGregor is printed as MacGregor and names with surname prefixes like "van Gogh" as Gogh.
Names converted from PGV are printed in upper-case and names added/updated in webtrees with the 1st letter in upper-case and the rest in lower-case.
