Change the template naming:

1. remove the _normal suffix, as it is not used
2. add a selector to look for the variable $lsbdistcodename being set and use that in selecting a template
this is useful to create a Debian_Etch.erb and a Debian_Lenny.erb which can have different values. For example
the Debian Etch version of openssh does not have the AllowAgentForwarding option, and if it is included, ssh will
fail to start
