D6679: Treat Button/ToolButton labels as plaintext

Restricted Application added a subscriber: Frameworks.

REVISION SUMMARY
  The label text gets treated as RichText/StyledText, which is required
  to display mnemonics underlined. Therefore it is necessary to manually
  HTML escape the label text, which unfortunately breaks mnemonics as
  escaped HTML contains ampersands.
  This commit fixes that by introducing a custom function to stylize
  mnemonics in HTML escaped text.

TEST PLAN
  Ran a modified knotificationdbustest with "<h1>&&a&ction</h1>" and
  "actio&n2" as actions. Result: http://i.imgur.com/xHifDBu.png
