Support for multiple project directories

[cdata]

As an Atom editor user,
when I open multiple project folders at once,
I want my code to continue to be linted,
so that I can be a productive software engineer

Currently, when more than one project folder is opened, I receive an error that says that the Polymer linter will only work with projects that have exactly one root directory. However, it is a fairly common work flow within Atom to open multiple project directories to make switching contexts easier to do. It would be nice if the Polymer linter continued to work in these conditions.

Also, it's kind of annoying that the error persists the way it does. I don't want to have to toggle off linting just to dismiss it :P

@rictic Hitting this too right now while developing on both the analyzer and editor-service. What is the underlying reason for reporting this error?

Oh, yeah, we shouldn't report it in a persistent way, just as a popup.

The underlying reason is just so that people aren't surprised when none of the IDE features work.

Okay but could we work around this; e.g. what is the issue we need to fix? Would like to fix this one for my own development workflow too 😄

I think we'll need one editor server per workspace. Which is fine if you've got, say, 2-5 workspaces. If you've got, like 100 workspaces (not naming names here or anything but such people do exist), and each of those workspaces has its own dependencies, then RAM usage could get kinda crazy high.

Hm. On the other hand, if we only instantiated an editor service when a workspace is first modified then everything would probably work out fine. If we also killed idle editor services, it would almost definitely work out fine.
