Resolves: rhbz#1020712 return all the selected scripts

What we want here is *all* the scripts in the range, that's the whole point of
using SCRIPTTYPE. We use this to determine the font to show in the fontbox. If
it's an exclusive script then we can show the font that that script, and if
there are multiple scripts we know to set it empty.

With the other intermediate bugs out of the way, this now appears to work
correctly.
