This reverts commit 80092dea5b.
After enabling both HTML and plain-text templating, I found that
this introduces a lot more complexity in the code than was desirable
for a project in this stage. The result looked fine, wrapping plain
text in <pre> tags. However, it was neccessary to keep duplicate
template files, for HTML and text. This was cumbersome, added a lot
of bloat, etc.
This feature is postponed to when there is more product.
