[ESS] Problem with ESS / R / tracebug under OS X

[Vitalie Spinu]

`install` in devtools keeps the source. load_all forget it. I sent a
pull request to Hadley to correct this. Feel free to use my branch till
it is merged: https://github.com/hadley/devtools/pull/319

Would it make sense to hook load_all on a key in dev-map? 

Say, C-c C-t l will search for the R package root from the current
file. Then ask the user for the directory, then issue load_all?

Unfortunately install, nor load_all play well with S4. I always have to
restart my R to reload the package.
