Can someone please land this pull request.  I have declined to include
any files where there are substantive errors that might interfere with
a build, so it should be safe.

When we added e-speak capability to the toolkit, we added a lot of
language names (the e-speak "voices"), a lot of language names can be
found translated in the Unicode Consortium's CLDR locale files.  I
transferred them over where possible.

Many of the same strings are in the Speak activity, but it appears
they may be using slightly different versions of e-speak base code (as
judged by the list of voices supported).  Can someone look into that?
