Use MDCTypography instead of MDFRobotoFontLoader directly.

[sdefresne, 2017/05/30 09:23:36]

Why change some calls like "[[MDFRobotoFontLoader sharedInstance]
regularFontOfSize:14];" to "[MDCTypography body1Font];" and leave others like
"[[MDFRobotoFontLoader sharedInstance] mediumFontOfSize:16];" to
"[[MDCTypography fontLoader] mediumFontOfSize:16];"?

I'd prefer if this CL was just a mechanical change from "[MDFRobotoFontLoader
sharedInstance]" to "[MDCTypography fontLoader]" if possible without introducing
semantic changes at the same time. WDYT?

Note: this comments applies here but also to all other locations where similar
changes are made.
