Fix BL-685: problems with getting proper language displayed on cover

Repair build for new libpalaso again
Add a ref to PalasoUIWindowsForms.GeckoBrowserAdapter.dll

The reference is added in hopes that it will cause the installer
to include this DLL, which is loaded using Reflection by
some Palaso code.
Tell installer explicitly to include DLL

Other Palaso DLLs are in the Chorus merge module,
but the new one we need must be specified explicitly.
Another libpalaso update
