+Allow @font-face rules nested inside @media rules
+
+Per MDN's At-Rules Nesting documentation, @font-face is allowed
+inside conditional at-rules like @media. However, cssutils was
+rejecting them with "This rule is not allowed in CSSMediaRule".
+
+This moves @font-face from the disallowed rules list to the
+factories dict in the CSS text parser, and removes CSSFontFaceRule
+from the rejected types in insertRule().
+
+Fixes #30
