Fixes custom ios schemes and file path issues on some IOS devices. (Supersedes #253)

[weareu]

This change is required for custom URL scemes and cordova-ios 6+ to function without file and new cordova-file-plugin hooks on URL. It also previously fixed problematic folders in #253 but is now required for later versions on IOS.

[weareu]

Also Added android-cordova 10+ changes where cdvfile is used on http. This causes the latest file transfer plugin to fail. I now send .nativeUrl to file transfer which interprets the file correctly and use cdfile via toURL or toNativeUrl or whatever as they all now return the http path for client side path or cached path.
