Subject: device/trezor: HF10 support added, wallet::API

- import only key images generated by cold signing process
- wallet_api: trezor methods added
- wallet: button request code added
- const added to methods
- wallet2::get_tx_key_device() tries to decrypt stored tx private keys using the device.
- simplewallet supports get_tx_key and get_tx_proof on hw device using the get_tx_key feature
- live refresh enables refresh with trezor i.e. computing key images on the fly. More convenient and efficient for users.
- device: has_ki_live_refresh added
- a thread is watching whether live refresh is being computed, if not for 30 seconds, it terminates the live refresh process - switches Trezor state
