Add Travis CI support (#44)

* Add Travis build with matrix for
  * openjdk8
  * oraclejdk8
  * openjdk10
  * openjdk11
  * openjdk-ea
* Use explicit maven compiler source and target version (source and target 1.5 have been removed from JDK10)
* Use latest version of Lombok (1.18.0) that works on Java 10
* Use latest version of Kotlin (1.2.51) that works on Java 10
* Use mapstruct 1.3.0-SNAPSHOT
* Manually symlink CA certs for openjdk10 to solve problem with https connections with sonatype_snapshots
