Title: check static cacheable dir exists before using gzippo

When gzippo can't find the directory, it serves an empty file. This checks whether the static_cacheable directory exists before using gzippo for it. [related issue](https://github.com/meteor/meteor/issues/177)

To reproduce the problem / solution.
from your meteor repo
```
cd docs
../meteor
```
and then load localhost:3000 from a browser with a clean cache, you should be prompted to download an empty file if you don't have the change.
