Webfonts: 'upper-case' numerals instead of text numerals

[mgavioli]

Context: Firefox under Linux Mint 17.1

In web fonts, the nice default text numerals of standard Junction fonts are replaced by boring, 'upper-case' numerals. Also, it seems not possible to activate the 'onum' feature via the "font-feature-settings" CSS declaration.

This applies at least to the .woff format (the one used by Firefox) and to all three weights.

Text numerals appear as expected if the standard font installed in the client is used instead of the web font on the server.
