Add jenv plugin
Initializes jenv and provides the jenv_prompt_info funtion to add Java version information to prompts. This function is stubbed in prompt_info_functions script to allow it to be safely called regardless of whether or not the jenv plugin is loaded. It also splits detection of the plugin/versions directory and bin directory to suppport the way Homebrew splits the jenv bin and data directories
