Reformatted progress messages, and fixed typo bug with variables

Changed the formatting of the progress message to provide more
information in a hopefully easier to read format. Also fixed
a nasty typo that caused a bug when several variables were being
referenced. ( '{$' changed to correct '${' )

Changes:
 - scripts/AddBackupUser.sh
	2014/6/7	Fixed a typo causing an error with variables
		( '{$'->'${' ). Reformatted progress messages.

 - scripts/SetupBackupServer
	2014/6/7	Reformatted progress messages.
