* updated to scalatest 3.0.5
* use scalatest runner instead of junit
Output is far more readable, and makes console (incl. travis) reports
actually usable.
Turned off test logs as error reporting is enough to figure out what
happens.
The only downside is that we can't use junit's categories to group
tests, like we did for docker related tests. We could use nested suites,
but that seems to be overkill so I just removed the categories. Users
will only have the possibility to either skip/run all tests.
* update scala-maven-plugin to 3.4.2
NB: This requires maven 3.5.4, which means that we currently need to
manually install maven on travis.
Also updated Docker java version to 8u181 (8u171 for compiling).
* 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
