Match same letter without accent in autocomplete

Also, this CL adds the medium version of the Open Sans font so it's
loaded correctly in the autocomplete box and elsewhere in the web.

The autocomplete also works when inputting any number of characters now,
it is no longer necessary to write at least 3 characters before it
worked.
