Adapt path in pipeline on importation

[adelphin]

Context
When using the feature "Import Data from another MP3 project", the pipelines are not imported. In some cases it could be convenient to import them. This feature would have to be more than a simple copy-paste, as paths in the pipeline structure are absolute.
So far I manually copy/paste my pipelines and modify the paths in each module of the pipeline, which can be tedious. Furthermore, the order of the module is not automatically conserved when doing so, which makes the task more complicated.

Possible Solution
An option to import pipelines that adapts the paths automatically would be great. It should be independent from the "import data" one, as some users might want to import their data only without the pipelines to avoid conflicts.
