v0.0.15 - turbo charging find

Even faster find than 0.0.14 by doing smarter caching (2+x faster than 0.0.14 and 5+x faster than 0.0.13). Also fixed a race introduced in the previous version. This optimization only kicks in when goofys detects application is sequentially reading a directory tree (either breath-first or depth-first).

Built with go 1.8.3
