Merge pull request #2312 from bootstraponline/doc_fix_master

Fix index pages for docs
Updated the app argument for the installApp, launchApp and closeApp to point to the device rather than appium. Also added a check for the "installToRealDevice" function to check if "launch" desired capability has not been set to false (as in that instance we want to manage installation and launching ourselves).

Changed the launch parameter to autoLaunch (including a check for launch desired capability and deprecation warning).
