wraith: Wraith does not work for HTTPS urls

Hi there,

I am trying out wraith for a site and unfortunately, it only generates empty images for a HTTPS site. Now, I have been looking at issues on Github and it seems that I have to put this setting in my config/component.yaml:

phantomjs_options: --ssl-protocol=tlsv1

However, it is still generating empty images.

When I try it with a non-HTTPS page, the screenshot is created as expected. So, I am guessing that this is related to HTTPS issue.

This is my config/component.yaml file for the HTTPS (non-working) version.

# Add as many domains as necessary. Key will act as a label
phantomjs_options: --ssl-protocol=tlsv1
domains:
  english: "https://www.viki.com"

# (optional) JavaScript file to execute before taking screenshot of every path.
# Can be used to reload current page with headers specified, or to dynamically
# AJAX in content, or all manner of other uses!
#before_capture: 'javascript/global.js'

# Type page URL paths below, here are a couple of examples
paths:
  home: /

# amount of fuzz ImageMagick will use when comparing images. A higher fuzz makes the comparison less strict.
fuzz: '20%'

# the maximum acceptable level of difference (in %) between two images.
# Wraith considers it a failure if an image diff goes above this threshold.
threshold: 5

# screen widths (and optional height) to resize the browser to before taking the screenshot
screen_widths:
  - 320
  - 600x768
  - 768
  - 1024
  - 1280

# the engine to run Wraith with.
browser:
  phantomjs: "casperjs"   # variant of PhantomJS that allows screenshots by element selector
  #phantomjs: "phantomjs" # PhantomJS, built on top of Webkit and JavascriptCore (like Safari)
  #slimerjs: "slimerjs"   # SlimerJS, built on top of Gecko and SpiderMonkey (like Firefox)

# the file in charge of taking the screenshot
snap_file: "javascript/casper.js"

# the directory that your base screenshots will be stored in
history_dir: 'shots_base'

# the directory that your latest screenshots will be stored in
directory: 'shots'

# choose how results are displayed in the gallery (default is `alphanumeric` if omitted)
# Different screen widths are always grouped together.
# Options:
#   alphanumeric - all paths (with or without a difference) are shown, sorted by path
#   diffs_first - all paths (with or without a difference) are shown, sorted by difference size (largest first)
#   diffs_only - only paths with a difference are shown, sorted by difference size (largest first)
mode: alphanumeric

Are there any sort of settings that I may have missed pertaining to HTTPS settings?

In case if it helps, my system informations are:

PhantomJS version 1.9.7 ImageMagick 6.9.2-5 CasperJS version 1.0.0 Mac OS X El Capitan Version 10.11.1

Thanks in advance for your help!
