marquee 1.0.0

• Fixed a bug in bullet placement that affected tight lists with multiple spans
  (#18)
• code spans gains a slight horizontal padding to let the background breathe a
  bit. Currently padding around spans doesn't affect shaping (i.e. it doesn't
  move text further from it's neighbors).
• Better adherence to margin collapsing rules of CSS. Any background or border
  will now prevent further collapsing
• Add force_body_margin argument to enforce that the body margin is not
  influenced by collapsing (allowing you to turn it off completely). This
  setting is turned on for geom_marquee() and element_marquee() (#23)
• Add support for rendering on graphics devices that doesn't support the new
  glyphs capabilities
• Inline padding now reserves space on the left and right side during shaping if
  the inline tag has decoration (background or border)
