Twenty Fourteen: Include Latin Extended font subset for Lato

[sixhours]

Lato is no longer correctly displaying Polish accented characters in certain browser/OS combos, including Firefox 32 on Windows 7 and Windows 8.

This is because as of August, Lato has changed its font sets:

Update, August 2014: The previous version of Lato included Extended Latin characters in the Latin subset. If you are experiencing problems, please select the Extended Latin (latin-ext) subset to render all European languages correctly.

Here is an example of a complete link tag that selects these subsets:
