Title: backport Windows fix onto 1-0-stable 

I wish this had made it into 1.0.4, but here's a pull request to hopefully make sure it gets into any future 1.0.x ... plugins are really broken on Windows without it.

Update load_plugins to be more Windows friendly. Uses File::PATH_SEPARATOR instead of hard-coded colon (':').
