Add bootstrap distribution mode (!config.dist.bootstrap=true)

In this mode the dist meta-operation does not load the project (but does
bootstrap it) and adds all the source files into the distribution only
ignoring files and directories that start with a dot. This mode is primarily
meant for situation where the project cannot (yet) be loaded due to missing
dependencies.
