* changes:
  Fix resource code and version attributes Create a new package setting object for updated system apps rather than moving around the same setting. This updates the resource, code and version correctly. For updating system packages, disable the package first which removes the entry from internal structures, create a new package setting, add it to list of user id's then rest of installation steps, kill the process if needed via ActivityManager then add this setting if everything was successful. This also fixes issues with updating values prematurely.
