Updated and fixed a few issues.

Previous build was not working in AWS OpsWorks on Ubuntu 14.04. I updated the URI to the git repository ( fixes #9 ), updated the version to the latest 1.78, updated required packages ( fuse-utils have been merged into fuse as of Ubuntu 14.04 - new code checks for existence of fuse-utils package and falls back to the fuse package ), and updated install command to open proper directory and executes commands according to the installation notes ( https://github.com/s3fs-fuse/s3fs-fuse/wiki/Installation-Notes ). Tested and confirmed in AWS OpsWorks on Ubuntu 14.04.
