-fix bug in cache for atlas import/export

-fix some menus
-fixed bug in out transition curves
-detect and remove file:/// in collada
-remove multiscript for now
-remove dependencies on mouse in OS, moved to Input
-avoid fscache from screwing up (fix might make it slower, but it works)
-funcref was missing, it's there now

+/**
+ * This class binds the service API to your application client.  It contains the IDownloaderClient proxy,
+ * which is used to call functions in your client as well as the Stub, which is used to call functions
+ * in the client implementation of IDownloaderClient.
+ * 
+ * <p>The IPC is implemented using an Android Messenger and a service Binder.  The connect method
+ * should be called whenever the client wants to bind to the service.  It opens up a service connection
+ * that ends up calling the onServiceConnected client API that passes the service messenger
+ * in.  If the client wants to be notified by the service, it is responsible for then passing its
+ * messenger to the service in a separate call.
+ *
+ * <p>Critical methods are {@link #startDownloadServiceIfRequired} and {@link #CreateStub}.
+ *
+ * <p>When your application first starts, you should first check whether your app's expansion files are
+ * already on the device. If not, you should then call {@link #startDownloadServiceIfRequired}, which
+ * starts your {@link impl.DownloaderService} to download the expansion files if necessary. The method
+ * returns a value indicating whether download is required or not.
+ *
+ * <p>If a download is required, {@link #startDownloadServiceIfRequired} begins the download through
+ * the specified service and you should then call {@link #CreateStub} to instantiate a member {@link
+ * IStub} object that you need in order to receive calls through your {@link IDownloaderClient}
+ * interface.
