Subject: [PATCH] feat(webfuse): eclipse cdt project (#17)
adds convenience run and discovery targets (for first build target)
allows usage of host container (volume mount/ dind)
fixes portable workspace configuration
adds makefile targets to CDT configuration
fixes localization
* adds eclipse-cdt project and necessary discovery for toolchain settings
* extends targets and fixes discovery
* renames CDT Eclipse project
* enables portable workspace docker-build on build server
