Some safety tweaks to shore up Android mainThread / NativeDelegate potential issues
Don't bother doing the NativeDelegate thread check for HTTP onSuccess / onFail; we know it's good and it can cause issues if a request queues up on Android just prior to onPause, which can cause the thread ID to change
Undid previous changes and instead changed show stopping Asserts into lmLogWarns
Updated iOS and Android icons / launch images to more updated specifications.  NOTE: Android build process renames 'drawable-xxxhdpi' to 'drawable-640dpi' (you can't just have 'drawable-640dpi' instead :/), so any apps that wish to replace that icon must have it placed in their 'icons/drawable-640dpi' folder, and not a 'drawable-xxxhdpi' folder.

Deleted some pre-shipped icons from some example projects as they shouldn't have been there.
