two commits: add missing symbols to Sami layout, remove duplicates, and redistribute

The first patch adds missing characters and dead diacritics, when compared to the corresonding Windows layout. The missing symbols were: Â, Õ, €, μ, and the dead grave, acute, ^, ¨, ~, and ˇ symbols. The symbols < > and Ŧ were already there but not in their proper places.

This brings the 'no(smi)' variant in line with what Windows has in the Sami Extended Norway layout.

The second patch then reshuffles some symbols to have them grouped logically, so that it becomes possible to remember where they are (as these symbols are not marked on the keys).

This partially addresses issue #337 (closed).
