Add details on how to use wildcard ssls

After reading the source code for hints on how to deploy wildcard ssls I found it was already supported.

The proposed change should make this feature easier to find.
s/ssl/TLS/g + domain name must match for wildcards

* Updated ssl to TLS as requested.
* Added information that names must match
Merge pull request #516 from eitland/patch-1
