[TIDOC-1413] Update JSDuck to 4.10.4

Additional gems to install:

  - gem install execjs
  - gem install therubyracer -v 0.10.1
  - gem install dimensions
  - ?? gem install rkelly ??
  - ?? gem install libv8 ??

Test by building the Titanium and Cloud documentation for both prod and dev.

Issues found during integration:

  - Unable to load guides with punctuation marks in the title
  - Links did not expand
  - Cloud method did not display REST method or URL
  - Links to Titanium API categories did not appear: http://docs.appcelerator.com/titanium/latest/#!/api

Notes:

  - Had to disable parallel processing.  Getting a strange error: "no _dump_data is defined for class Proc"
  - Warning system changed, so receiving more warning messages.  Probably can disable with a CLI option.
