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.

+Reachability
+
+========================================================================
+DESCRIPTION:
+
+The Reachability sample application demonstrates how to use the System
+Configuration framework to monitor the network state of an iPhone or
+iPod touch. In particular, it demonstrates how to know when IP can be
+routed and when traffic will be routed through a Wireless Wide Area
+Network (WWAN) interface such as EDGE or 3G.
+
+Note: Reachability cannot tell your application if you can connect to a
+particular host, only that an interface is available that might allow a
+connection, and whether that interface is the WWAN.
+
+========================================================================
+USING THE SAMPLE
+
+Build and run the sample using Xcode. When running the iPhone Simulator,
+you can exercise the application by disconnecting the Ethernet cable,
+turning off AirPort, or by joining an ad-hoc local Wi-Fi network.
+
+By default, the application uses www.apple.com for its remote host. You
+can change the host it uses in ReachabilityAppDelegate.m by modifying
+the call to [Reachability reachabilityWithHostName] in
+-applicationDidFinishLaunching.
+
+IMPORTANT: Reachability must use DNS to resolve the host name before it
+can determine the Reachability of that host, and this may take time on
+certain network connections.  Because of this, the API will return
+NotReachable until name resolution has completed.  This delay may be
+visible in the interface on some networks.
+
+The Reachability sample demonstrates the asynchronous use of the
+SCNetworkReachability API. You can use the API synchronously, but do not
+issue a synchronous check by hostName on the main thread. If the device
+cannot reach a DNS server or is on a slow network, a synchronous call to
+the SCNetworkReachabilityGetFlags function can block for up to 30
+seconds trying to resolve the hostName. If this happens on the main
+thread, the application watchdog will kill the application after 20
+seconds of inactivity.
+
+SCNetworkReachability API's do not currently provide a means to detect
+support for GameKit Peer To Peer networking over BlueTooth.
