v0.2.0

• Video-embeds are now working within @bastianallgeier's (columns…)-tag when having markdown.extra enabled.
• Removed the unnecessary color-placeholder <div> by now using the <figure>'s pseudo element to display the color-overlay while loading.
• Added an option (both in kirbytag and in config) to disable the <video> to be wrapped with a <figure>
• Minor: No longer empty sizing styles are applied when no sizing is given.
