Edit pipeline io

[jmlord]

Can now edit input and output labels and descriptions in right pane of pipeline editor. Labels dissalow line breaks (allowed in descriptions)

Maybe say that the editing of the descriptions and labels needs to be copied and then pasted in the pipeline .json to take effect? Otherwise it is not super obvious.

We already had this in the local setup section:

When modifying pipelines in the /pipelines folder, servers do not need to be restarted:

• In the pipeline editor, click save, paste the file to your file in the pipeline folder and run it from the "pipeline run" page.
• When adding or renaming pipelines, refresh the browser page.

I added this in the IO part:

Once edited, make sure to save your work before leaving the page.

Then clicking save pops up the alert telling you to copy/paste it and use git.
