    Add optional yalign argument to Utils::mk_label() method
    
    As part of the work on bug 652044 - uses deprecated APIs, selectable
    vertical alignment was defaulted to ALIGN_CENTER for all labels.  The
    relevant commits can be viewed in comment 26 of said bug report.
    https://bugzilla.gnome.org/show_bug.cgi?id=652044#c26
    
    For multi-line labels a vertical ALIGN_CENTER value is not
    consistently aesthetically pleasing.  This becomes obvious when a
    single-line heading label is paired with a multi-line value label.
    To improve the aesthetics, a vertical alignment of ALIGN_TOP is
    preferred.
    
    Hence re-add the ability to optionally specify a vertical alignment for
    labels.  If a yalign value is not specified a default vertical alignment
    of ALIGN_CENTER is used.
