Fix line endings

Some text files were previously stored in the git object database bearing CRLF as line terminators.
This fixes those files.

@yvesgoeleven I've checked the fonts (src/ServicePulse.Host/app/fonts/FontAwesome.otf, src/ServicePulse.Host/app/fonts/fontawesome-webfont.ttf). They've been unaltered since (at least) 666ca1ed495232b85ee51a7b9bfb49931dc0374f. No need to re-add them.
