Stack level too deep error when used with awesome_print >= 1.6.0

[sbonebrake]

Error below:

 Failure/Error: Unable to find matching line from backtrace
     SystemStackError:
       stack level too deep
    /.rvm/gems/ruby-2.1.2/gems/awesome_print-1.6.0/lib/awesome_print/ext/ostruct.rb:14

The class at https://github.com/appium/ruby_lib/blob/master/lib/appium_lib/awesome_print/ostruct.rb is already included in awesome_print 1.6.0, so I think the double calls to alias_method's are creating an infinite loop when 'cast_without_ostruct' is called.

We either need to require awesome_print 1.6.0 and remove the ostruct.rb file from ruby_lib or modify it to be backwards compatible.
