Removed config from old versions.  Build pack is only supporting the three most recent versions of a package.
Removed argument for --latest.  Going to rework this aspect of the program.
No code changes, just reorganized methods.
Changed get_latest_version to look at an existing directory of binaries and to compare version numbers as you would expect (left to right, each segment compared individually).
Modified get_latest_versions to work for versions with leading zeros.  Modified generate_build_list to take index and allPkg args.  Index allows specifying where to write the index, allPkgs picks between dumping all packages or just the latest ones.  Modified argparse code to take the extra arguments.
Fixed bug preventing base-url argument from working.
Including index-all.json, which contains all the packages and index-latest.json which includes the latest set of packages.  You can download them with the command 'bin/binaries download --index <file> <path-for-downloads>'.
Updated the docs with the new instructions for 'binaries download'.
Added 'binaries zip' command that prepares a zip file of the build pack and the specified binaries.  This can be used in conjunction with CF's create build pack command.
Changed 'binary path' to binary_path.  Output in help looks nicer.
Adjusted help messages for sub commands.
Updated documentation with latest instructions for bundling binaries with the build pack.
 - Modified NewRelic extension to more gracefully handle errors.
 - Updated NewRelic tests to be more flexible and easy to extend.
 - Added test for NewRelic w/HHVM which should not install NewRelic
Modified how build pack zip is generated.  Now includes empty directories and symlinks.
Upgraded to Nginx 1.5.13.
Removed Nginx 1.5.10.
Updated index files to include Nginx 1.5.13.
Added initial info for Nginx 1.6.0 and 1.7.0.
Updated binary lists.  Full index now has Nginx 1.6.0 & 1.7.0.  Latest list now shows the latest version for each major release (i.e. first two places from the left).
Modified script to generate list with latest version for each major version (left most two places in version number) of a package.  Also, refactored code to generate the list of files for a version into it's own method.
