I added type and subtype attributes for the elements in the lists in names.xml

I also added n="1" attribute for Old Norse items that contain an "eth" or "thorn" or an <addName> that requires a translation. Only the first entry for keywords will be displayed if there is not an n="1" but the first and second entries will be displayed if n=1" is present on the first entry.

The next task is to itemize my use of <persName> and <name> as <gi> tags in my <encodingDesc>, and then get on with changing <persName> and <name> into empty elements in all the files.
