Removed spacers, fixed update output

Removed spacers because they were really ugly to read.

The output of the update checker was blank if there were
    no updates available. Fixed it so that it explicitly
    says there are no updates.

Added the $NOTIFIERFILE variable so that the long
    path of the update-notifier file isn't repeated.
