Support CSS margins for block elements in HTML labels

PR Description:

Adds support for CSS margin properties for block elements in
the text renderer. Specifically:

• This is available for block type elements only, eg DIV, P, H1-H6.
• Margins are NOT available for spans or other non-block content (due to Qt limitations)
• Margins can be specified in pt units only
• Margins can be specified either via "margin-left: 5pt; margin-right: 10pt" etc, or "margin: 5pt 0pt 10pt 0pt"
• Negative margins are supported for the bottom margin ONLY (due to Qt limitations)
