mob v2 is not compatible with latest MobMuPlat for android

As in the new android apk for MobMuPlat, files are stored within the app file system, subdirectories aren't anymore supported. This is problematic for my [mob] project that largely uses abstractions stored in subdirectories. 
The develop branch https://github.com/jyg/mob/tree/develop is an attempt to solve this big issue.
