There is a big difference among files which are on the ProjectFileSystem
(the FS which contains the project definition, the project file system
always implies a single Project) and file object which are belonging to
the project(s) but are on the other filesystems (local, ftp,...).
These fileobject can belong to more than one Project, so the Project is
not implied by the FileObject and Project.findAll must be used to return
all these projects. The problem with findAll is how to find out which
project to choose from the returned array.
