v0.3.0

Added

• tags.Parse reads a tag back from the name String prints, modifiers
  included ("function(definition(variableName))"), so a theme kept in JSON or
  TOML can name the tags its TagStyles style.

Fixed

• A line-through sits across the text in every font. With fonts whose
  x-height x/image reports negative (DejaVu Sans Mono), a Strikethrough
  token was ruled below the baseline instead of across its letters.
