Add browse author and title by script

[davidamichelson]

Please add the same feature as in the gazetteer where the option to browse information by script is available. (see screenshot)

Do note the following difference, in the Gazetteer, the browse is (I think) using a xml:lang attribute to sort by language, but we just want to use unicode range. (or if you prefer, we could mark the data by lang for you, would that be better?)

So the labels should be as follows:

For titles or names which begin with 0020 — 007F Latin, label the tab as "Latin Script"
0370 — 03FF Greek
0400 — 04FF Cyrillic
0590 — 05FF Hebrew

This issue is not finished drafting

If it is possible to add the lang tag into the TEI that would be better, it looks like most of the titles have mixed language titles, which makes the sorting a little difficult without the language tag.
