Try reducing the large artifact files

Is your feature request related to a problem? Please describe.
The size of the artifact files in the pre-release 1.3.0-b1/2 is quite large compared to previous releases.
Check if they can be reduced in the size by omitting large test files and stripping the binaries.

Describe the solution you'd like
A smaller size of the artifacts would be nice. So instead of 160 MB which they have now a size of 20 to 50 MB would be ok. The previous size was about 12 MB.

The folder ./res/exampleFilesVersion1_2/Databases contains 150 MB of database files. These files can be removed from the artifact files and be collected in a separate database artifact file. Instead of using 150 MB in each artifact (6 times 150 MB), we use only one time 150 MB in the single database artifact. This saves us 750 MB!
