Merge branch 'hotfix/readme_russell' into develop
Changed lightning symbol for root to
Added ir_black colour scheme file for iTerm 2.
Add default user for agnoster theme to zshrc template.

Without a default user set, the LPROMPT looks like

  user@hostname > dir >

With the user set to the currently logged in user, the prompt becomes

  dir >

This can be useful when ssh-ing into remote machines, as the hostname
will appear. However, on a local machine the user most likely know who
they are and the name of their computer, so it is not required.
Changed default theme to agnoster-alt.

This matches the default theme used in this configuration.

This configuration is for with a folder ~/bin and for use with MacPorts
(/opt/local/bin).
