Display output of given script

Display output of any executable script set by script_path
Pay attention. The output must be one liner, or will break your i3status
The script should not have any parameters, but it could work

Configuration parameters:
    - cache_timeout : how often we refresh this module in seconds
    - script_path   : script you want to show output of (compulsory)
    - color         : color of printed text
    - on_click      : read goo.gl/u10n0x
    - format        : see placeholders below

Format of status string placeholders:
    {output} - output of script given by "script_path"

i3status.conf example:

external_script {
    script_path = "/usr/bin/whoami"
    format = "my name is {output}"
    color = "#00FF00"
