This changes the keystore data format, wallet format and IsMine logic to detect watch-only outputs based on direct script matching rather than first trying to convert outputs to destinations (addresses). The reason is that we don't know how the software that has the spending keys works. It may support the same types of scripts as us, but that is not guaranteed. Furthermore, it removes the ambiguity between addresses used as identifiers for output scripts or identifiers for public keys. One practical implication is that adding a normal pay-to-pubkey-hash address via importaddress will not cause payments to the corresponding full public key to be detected as IsMine. If that is wanted, add those scripts directly (importaddress now also accepts any hex-encoded script). Conflicts: src/wallet.cpp
