* Renamed eclair-node-javafx module to eclair-node-gui
* (build) javafx installer uses project version
* (build) Streamlined capsule names
* (build) mvn generates installer only with `installer` profile. The windows installer does not need to be created in common cases. Decreases `eclair-node-gui` module building time by ~ 1 min
* (readme) updated the `run eclair` commands with the new capsule names
* Added help option in command line; added version in logs
* Version and commit id added in manifest (use Specification-Version for commitId)
* (gui) version in about is now dynamic; ESC key closes about
* Excluded unused protobuf dependency
* Update README.md
* BOLT 4: create return packets for failure messages
* bolt 4: add low-level methods for returning error messages
* BOLT 4: return shared secrets along with the onion packet
* codecs: minor fix the UpdateFailHtlc codec
* BOLT 4: return htlc failures
create and propagate htlc failures as per BOLT 4
* update tests
* channel: publish short channel id when restoring data
and not on reconnection
* channel: remove "channel update" parameters from Commitments.sendAdd()
* channel: send "add htlc failed" to relayer
and a more informative message to the sender through handleCommandError
* keep shared secrets local to PaymentLifeCycle
CMD_ADD_HTLC should just know the onion packet (as before), not the shared secrets
* relayer: handle failure cases
wrong expiry, amount, ...
* added a simple test on the fail workflow
* added a 'channel-capacity-exceeded' test
* make PaymentSucceeded and PaymentFailed children of PaymentResult
* relayer: ChannelUpdates should be stored in a Map, not an Option
* reply with update_fail_malformed_htlc when the onion is not parsable
* channel: handle 'update_fail_malformed_htlc' in Shutdown state
and add tests
* minor: AddHtlcSucceeded -> AddHtlcSuccess
* use bitcoin-lib 0.9.10
* use bitcoin-lib 0.9.9
* use scalar/point/public key types instead of binary data
* minor fix: scalar are encoded on 32 bytes

numbers between 0 and 16 were not encoded properly in redeem scripts
* removed some useless calls to constructors
* implement a basic tx db that stores how to spend revoked transactions
it's a simple db that stores spending tx indexed by their parent id
* bumped akka version to 2.4.8
* fixed wrong data type in CLEARING and NEGOTIATING handlers
* added a few common handlers
* moved sendAdd/receiveAdd logic to Commitments.scala
* moved htlc index to Commitments class

* added a log to unimplemented function 'handleTheirSpentCurrent'
* changed ascii art helpers->handlers
* fix misleading comments and code in Channel
* removed unused imports
* added test showing bug when two htlcs share the same r
* added a failing test showing that punish tx output isn't p2wpkh

* use P2WPKH instead of P2PKH in our "punishment" tx
* fix failing test
* added helper methods in test
* fixed test
