Bugs

• [#884] We now properly enforce RFC-compliant date headers for Last-Modified file headers. If you run actionhero on a computer where English or a western-style calendar is not your default locale, the format of Date().toString() might not be compliant. Strict checks for this were introduced in node v4.3.0. More detail here http://www.alexkras.com/typeerror-the-header-content-contains-invalid-characters
• [4e2d3a8] Task error reporter now properly returns local worker's ID

• [7fa7538] Ruby gem and version upgrade for static site (www.actionherojs.com) generator to fix ruby security issues
