Change the name of "Normal" draft to casual draft

When I read normal, what comes to mind is ranked but without ranked part. But that is not what "normals" are in draft mode and create a false impression of what ranked mode actually plays like. The much more fitting name would be casual draft. Which sets the tone for what the type of games will be having instead then when people read normal.

Maybe a couple seasons ago this wasn't the case. But since last season, casual is starting seem like the much more appropriate and accurate description for normal draft then the word normal.
