Fixed use of deprecated 'create' functions and various fixes.

The Parkour tutorial with JavaScript v3.0 was using the deprecated 'create' function for instantiating objects instead of the keyword 'new'. This commit changes this by using the keyword 'new' where 'create' was used. The code, docs and zip files have been changed.

Fixed use of the cc.c4b method call and invalid resources in chapter 9. Added the /res/TexturePacker folder to chapter 8. This folder was mentioned in the tutorial but was not supplied.
