implode() syntax error in Comment, Node, and User resource

I noticed this in the latest dev version (generated 2011.03.14). The Resources tab when editing an Endpoint results in fatal errors. It is just a typo that was made somewhere.

implode currently looks like implode(" ", ("\n", ..... I am not sure if Services switched to using new line or a space. Please correct the patch accordingly.

I only have TortoiseGit installed at the moment so the patch will need to be run with "patch -p1", and can't run through automated tests, but it works visually.
