Fieldsets for variables are vague without examples

[jasonmarkle]

When defining your custom data via the given field, some field names leave a lot of ambiguity to the naming convention of the data you need to insert.

Entering $wvu-gold, wvu-gold, or gold into the field for masthead_color:

One of these yield a gold masthead, whereas one would expect a gold masthead bg to be output as if you were defining it it the pattern's variable itself in the theme files.

Edit: Might have been some server lag earlier, gold works as intended, but the point is still valid. Once we get documentation rolling I'm sure this will be an easy issue to deal with piece by piece.
