add bundle using bnd's sub-bundles via -sub: *.bnd

bump tycho version to 4.0.10

gitignore MacOS .DS_Store files

add bundle using bnd's sub-bundles via -sub: *.bnd

see the bnd.bnd of the new tycho.demo.markdown bundle.
it uses the -sub: *.bnd instruction to create 2 jar files based on the other .bnd files (api.bnd and impl.bnd)

this build currently fails and we want to use that to fix tycho to make it pass.
It seems that tycho currently does not recognize the 2 (sub) jars so it cannot find them as dependencies for the HelloWorldService
