ported over the backup functionality from the old build to the new while
making few tweaks
instead of packaging up all files in the site to create massive zip
files, now a list of files is created for the user and blog directories
that the system will use to download and put them in the appropriate
directories, resulting in a such slimmer backup file.
archiving images my be added at a later date, but will be kept seperate
from the current back up process
