Proof of concept for websocket-based preview generation
Move this to public so it's accessible for testing purposes
Scale the preview
add viewBox property to the svg for scaling
margin_right wasn't behaving correctly
remove duplicate code
Initial kinda working ws-based simple editor preview
need to call .to_i for the font size as it might come as
a string from the ws-call
Move the simple-editor styles to the new id's
Also bind to change events for select boxes
tag all simple editor fields with data_simple_field
Merge branch 'ws_simple_editor'

Conflicts:
	app/assets/stylesheets/slides.css.scss
	app/views/slides/_simple_edit.html.erb
