Update transparency scores for hardware wallets

This is an attempt at providing appropriate transparency scores and texts for hardware wallets (TREZOR and BTChip) (see #564 #545) (@slush0 @btchip, feel free to give your comments)

At the same time, this pull request raises the bar a little for all wallets by giving all non-deterministic wallets a score title saying "Basic transparency" instead of "Good transparency", which better reflects that higher levels of transparency is possible.
