add ssl.conf template for rhel, add mod_ssl for rhel, change domain.com....

proposed changes to resolve issue #'s 17, 18, & 19.  

#19 - adding mod_ssl created an issue of having two 'Listen 443' which would cause the service to crash.  An ssl.conf template was added to comment out this line as well as the default ssl virtual host that is created with the file.  This is now commented out in the template.

#18 - mod_ssl was not being installed on RHEL based systems.  This was added when other apache packages are installed

#17 - domain template was being named with the .conf extension and causing the template file to become active, this has been renamed to default.template on both RHEL and Debian based systems.

Tested on both CentOS 6.5 and Ubuntu 12.04
