File watcher should handle changes to garden.yml files

Another thing - we also don't currently pick up new modules when they're added.

It occurs to me that we should perhaps change a bit how we handle file watching. Instead of putting multiple explicit watches on individual directories, that we should watch all source directories and then filter and route events as they occur. @thsig did you explore that when you wrote the watcher logic?

I thought of that possibility, but back then, I didn't think of the case when module/project config, so I chose the simpler implementation for starters (since there's no need for filtering/routing for per-module watches).

I agree we should make the change you outline above to the file watching logic, i.e. using a single project-wide watch, where change notifications trigger reloads of the appropriate modules (if any), and where processModules is restarted when that's called for.

The file watching part of it, at least, should be fairly straightforward.
