Template engine doesn't support else

[itderrickh]

In the template-engine project the markdown states that you can use if else statements, but the code in the template-engine doesn't support it and also none of the test cases test for else statements either.

See markdown file:

Search for {% else %} to jump to the issue

Thanks for catching this @itderrickh . I've removed mention of the {% else %} tag in the couple of places where it was mentioned throughout the chapter.
