Icon set is out of date

[bengourley]

Hey there, thanks for publishing each part of semantic as its own module! Makes it really easy to mix and match with other tools.

It looks to me like the icon set is out of date in this module. For instance with the Google logo icon, it has the old serif style 'g' whereas the version here is the newer sans-serif 'G'.

Would it be possible to publish an update? Cheers
