This is a worrisome solution for #164. I am not totally comfortable with the solution, but the system Open dialog's behavior does not seem to be configurable. If the WORKSPACE file is a softlink, the Open dialog resolves the soft link to the canonical path. So to support this use case we need to detect that we are in a non-root directory of the Bazel workspace. This could get nasty as Bazel supports nested workspaces, but the solution seems to be ok since it makes sure the found WORKSPACE soft link is pointing to the canonical file identified by the user.
I also added a pref to disable this feature, just in case there is trouble with it. A follow on PR will clean up the prefs stuff, it is a little rough.
