renamed "stylename" parameter in canvas.renderText to match text template element
more default arguments; renderText and drawImage can now be used the same as their template.element counterparts
Merge branch 'master' of github:frezned/card-renderer
fall back to PIL default font rather than Candara
added direct template.text, image and function methods as alternatives to template.element
name element is now optional on renderer.style; you can pass in the returned string
