#7 group inside repeat has extra labels

[Micah Dubinko]

Ordinary form controls, when they are repeated inside a <xforms:repeat> with appearance="compact", the <xforms:label>s are used to create table headings. This is desired behavior.

When a group is inside a repeat, however, the label appears in the table head AND on every subsequent repeat. This is undesired behavior. Groups should work the same as evertyhing else.

The extra, unwanted labels are generated with a class of xforms-group-label.
