Fix paste

Got the fix by comparing the code with https://github.com/jackpal/Android-Terminal-Emulator. Nothing more to add so yeah.

Also for this file you can readd these

    int[] colorScheme = settings.getColorScheme();
    setBackgroundColor(colorScheme[1]);

For this file "term/src/main/java/com/offsec/nhterm/TermViewFlipper.java", not sure why i removed these.
