LND 0.13

[Jasonvdb]

Contains breaking changes

• Updates Lndmobile to 0.13
• Original unlocker bug seems to be resolved so a lot of native Swift/Java code could be removed. GenSeed, InitWallet and UnlockWallet are just called from the JS now .
• LND now has it's own state service so it's no longer required to keep track of the current state and it's updates in the native code.
• Refactored state service and wallet unlocker functionality into their own service classes.
• There is a bug with the protobuf files where having multiple proto files all using the same namespace causes some issues. Before updating the proto files from LND's repo we need to add a prefix to the package name. i.e for the walletunlocker.proto we need to change package lnrpc; topackage wu_lnrpc;.
