adc_sync - now uses rsync instead of unison.
add_user - password variable now quoted.
setup_samba - adc_sync cron job set to 30 mins.
smbwebclient - modified for seamless reverse proxying.

This now installs one directory lower so that it can be run through a reverse proxy
Install path is now /var/www/html/smbwebclient/smbwebclient
This looks odd but means it is now accessed from https://server:50000/smbwebclient
which can be set to be accessed through a reverse proxy.
