Update Beremiz translations and list of translators

Added Turkish, Romania, Portuguese, Polish, Dutch, Hungarian.
Most existed translation are updated.

Use the list of supported by app translations instead of supported translations by wx

This will make possible to translate application into locales, that
are not explicitly supported by wx: for example, 'pl' or 'bn_BD', 'bn_IN'.
