Added proxy_set_header and vhost_cfg_prepend to the ssl vhost template.

proxy_set_header and vhost_cfg_prepend was missing from ssl vhost template.

proxy_set_header is important in cases where nginx is used as a SSL proxy and the backend application need
to have custom headers appended to.

For instance Wordpress need headers like 'X-Forwarded-Proto https' to work properly with SSL proxying.

Seems to be failing in ruby 1.8.7

That was due to an issue with the tests which is now fixed.

@haraldsk if you rebase this should pass. Please also consider adding tests for this new functionality, you can base this on the new tests in spec/defines/resource_location_vhost.rb

I just hit this issue as well. @haraldsk - are you planning to update this PR?

[grooverdan]

opps, #201 and #202 also covers this fix

[grooverdan]

and this one at least partially fixes the test cases for them.

[haraldsk]

@jhoblitt Haven't had the time. But it seems #202 is merged and all is good.

Way old. Thanks for taking a pass at this... going to revisit when 🕐 allows. Please reopen and rebase if you wanna take another pass at this.
