[stringtemplate-interest] Outputting java.util.Properties

[John Snyders]

Properties works like a map but it is not derived from Map so you can't do
<props.keys> to enumerate the keys.

"keys" is a pseudo property of Map that returns the keys in the map.

Usually with Map or Properties you want random access to the values as in
<props.one>

If you want all the key value pairs and you can switch to Map (or wrap
Properties in a class that implements Map) then you can do this:

 <props.keys: { <it> <props.(it)> };separator=", ">

Note how I used the separator option rather than first and rest as you had
below.

The only issue with this is you get the keys in any order unles your map is
ordered like TreeMap.

Hope this helps
