Title: Fix variable access warnings and an error

When I run this module on my puppet nodes (v3.3.2), I get the following error:
```
Error: Failed to parse template ssmtp/etc/ssmtp.conf.erb:
Filepath: /usr/lib/ruby/site_ruby/1.8/puppet/parser/templatewrapper.rb
Line: 81
Detail: Could not find value for 'puppetmaster' at /tmp/vagrant-puppet/modules-0/ssmtp/templates/etc/ssmtp.conf.erb:5
at /tmp/vagrant-puppet/modules-0/ssmtp/manifests/config.pp:23 on node web.the-jci.org
```

I don't know why "puppetmaster" isn't defined for my servers, but I fixed the error by simply wrapping the references to puppetmaster inside an "if" block.

I also got the following warning, which I fixed as well:
```
Warning: Variable access via 'puppetversion' is deprecated. Use '@puppetversion' instead. template[/tmp/vagrant-puppet/modules-0/ssmtp/templates/etc/ssmtp.conf.erb]:5
(at /tmp/vagrant-puppet/modules-0/ssmtp/templates/etc/ssmtp.conf.erb:5:in `result')
```
