added FAQ question on how to tune a backup
ez-apt-install.sh: cut and paste convenience script that can be piped from wget

Rational: make installation on Ubuntu/Debian ridiculously easy

Usage::

    # I feel lucky
    wget -O - -q https://raw.github.com/turnkeylinux/tklbam/master/contrib/ez-apt-install.sh | PACKAGE=tklbam /bin/bash

    # I feel cautious
    wget https://raw.github.com/turnkeylinux/tklbam/master/contrib/ez-apt-install.sh
    cat ez-apt-install.sh
    chmod +x
    ./ez-apt-install.sh tklbam
created detect-profile internal command

rational: primitive for generic Ubuntu/Debian support
profile_id detection for non-TurnKey systems
synced tklbam-init.txt with embedded usage
updated FAQ to clarify supported Linux systems, storage backends and databases
