Problem in Mid-Century template set

There is a very small, but significant code error in the Mid-Century template set that affects the ability to have threaded replies to comments. Luckily it's an easy fix...

The original line (in the comments module) looks like this:

<input type="hidden" id="comment-parent_id" name="parent_id" value="<$MTCommentParentID$>" id="comment-parent-id" />

Notice that the first id attribute has an underscore where there is supposed to be a dash, and in fact the id attribute is duplicated.

Easy fix, just replace with:

<input type="hidden" id="comment-parent-id" name="parent_id" value="<$MTCommentParentID$>" />
