Bugfix

Fixes a bug that throws an error when no accept header was send by the client.

Vary Header

In this release the Vary: Accept http header is added to allow caching proxies to distinguish between different files that are send.

Updating dependencies

This release is a small maintenance update that updates dependencies and cleans up some lines of code.

• MD5 is removed in favor of the crypto module
• webp-bin is replaced by the better maintained cwebp-bin module
• mkdirp and mime are updated to their most recent versions

Further the default value for the cache directory (options.cacheDir) is changed from __dirname + '/../../webp-cache' to path.join(process.cwd(), 'webp-cache').
