Highlight HEAD and refs/meta/config

In the ProjectBranchesScreen the entries for HEAD and refs/meta/config
are special since they do not represent ordinary branches but have a
special meaning. This is why they are already displayed at the top of
the table. With this change the rows for HEAD and refs/meta/config
will be printed with a special style to highlight them even more.
