added download feature for iOS port

required libs: 
    * ZipArchive - Obj-C impl of zip
    * asi-http-request : http request help to assist with asynchoronous downloading of files
    * minizip : support for ZipArchive
    * 
Added default splash screen for iOS app.  (using the Wagic background to keep it neutral to module)

TODO: refine handling for iPad splash screen
    * add selection screen and input screen for location of downloadable content. (ie core files, image files, etc )
    * add support to opt out of backing up to iCloud for core files. Right now iOS will automatically backup all files under Documents folder to iCloud.  Consider only allowing player data to be backed up to iCloud.  All graphics and other assets are considered volatile.
