Update qt-install

added mysql and dovecot to start
moved qt-setup-firewall to start last

[shubes]

What's the reasoning for putting qt-setup-firewall last?

[PaulSipos]

Probably because qt-install calls qt-setup-firewall which sets the rules to drop packets from internal networks on all interfaces except the loopback interface (lo) before the rule to allow communication over established sessions.
The effect is that if you run qt-install over ssh from an internal network, you get cut-off before the installation is completed (actually before it starts).
Not sure once the system figures out your session is no longer communicating that it doesn't kill all children processes interrupting the qt-install.

Suggestion: move "iptables -A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT" before the DROP rules.
