connect config-facade with the new BasicSetup implementation
to fetch values from setup.ini, instead of the (not implemented)
Config-system. Hook this new lookup mechanism into the
plugin loader to retrieve the search path from there
- use custom builders
- clean up specification of target paths
- generated executable is fully relocatable
- read a bootstrap INI instead of compiled in searchpath
the installed lumiera exe can even be started...
...well with a bit of cheating: you need to cd into the lib/lumiera
because the PLUGINPATH problem isn't solved yet
