additional file name translation rules

[christiansteinert]

Opencms only comes with file translation rules for the most basic types of characters. It would be good to have more translation rules by default so that latin characters with diacritical marks will be converted into their basic letter forms without diacritics.

Please take a look at pull-request #70 for a proposed patch against the latest version of opencms-vfs.xml. The patch adds translation rules for all latin character versions with diacritical marks. The characters are encoded as numeric XML character entities.
