Lfl loom custom url schemes

That's right, I don't think it will work.  I had done that back for Dolby Audio (platformMobileAndroid.cpp, line 314), and I ended up getting corrupted strings back.  I saw this CCString with autorelease() method used by getPackageNameJNI() in SystemInfoJni.cpp, implemented it, and it worked for me.

So, straight jstring2string() pointer returning to LoomScript doesn't preserve the memory and it gets trampled it seems, so I have used this other method since I first discovered that and it works fine.
