Please review a relatively simple changeset to introduce and use a new
class to explicitly handle HTML entities within an HtmlTree. This allows
for some customized behavior (specifically a character count of 0 for a
zero-width space) and avoids an otherwise unnecessary use of the RawHtml
class.
In addition to introducing the new class, the use of Contents.SPACE and
Contents.ZERO_WIDTH_SPACE is updated to use the new entity constants.
FInally, explicit uses of strings "<", ">" and "&" are updated
to use appropriate new entities.
