Added all hackbytes.com JavaScript files.

Most hackbytes-specific JavaScript files are minimized by the Closure
Compiler. These files are denoted by a prepended underscore in the file
name. The hackbytes build script ensures any necessary license notices
are also included in the minimized hackbytes.min.js file.

Other JavaScript files include plugins or serve as a backup to
CDN-hosted files that are part of a library (Bootstrap, jQuery, etc.).
