Roughly works but need more work and polishing. The workspace plugin
is temporarily disable waiting to be fixed.
Now the application does no longer 'chdir' into the project directory
and we removed the concept of project's directory (core.project_dir)
and project's files (core.project_files). Instead we have always a
project that can contain zero, one or many directories or files.
No directory is special within a project, there is no longer a concept
of project's directory.
WIP adapting open-file command to open a directory
Crash when adding a file into the project
It make sense to not put the initial '/' in the filename as the name
is relative to the top directory it belongs to.
By removing the the initial '/' in the filename we can re-introduce the
variable
core.project_files
to stay compatible with standard Lite. The project_files variable will
always point to the files table of the first entry of
core.project_directories.
