Version 1.10.4

Versions 1.10.2 and 1.10.3 have not been released publicly.

Fixes:

• The JaCoCo report task correctly ignores test files
• Fix to test-legacy task

The main change is the generation of the Manifest file in the case of "fat JAR" files. The manifest correctly exports a package name and a version attached to this package; fat JARs that bundle multiple packages preserve that information, so that it is possible to inspect this file to see exactly what packages are included and the version number for each of them.

In addition, the fat JAR no longer includes multiple copies of the same file (in case multiple source JARs contain it), which could cause version clashes and a lot of confusion.
