Speed up android livesync

[Fatme]

tns run android command transfers all files on initial sync. Actually there is no need to transfer all files on device because the installed .apk contains them. So after the application is installed on device, calculate the hashes for files inside \plaforms\android\app\* and upload the hash file on device. When the initial sync is executed {N} CLI compares the hashes and no file is transferred on device because all files are the same (no change is occurred). This PR speeds up the initial livesync with around 15seconds for angular application.
