Bug in #dlig generation

If automated, f_b takes priority over any other ligatures which means f_f_b will be ignored.

fixed it. Thanks.

Also f_f, f_f_l and f_f_i ligatures refuse to go into dlig. Somehow adding a suffix don’t put them into the feature either.

If I use f_f_i.dlig it ends up in the dlig feature.

One more thing - onorthodox ligatures like r_t, f_y and such get arranged alphabetically. This means r_t is above r_t_i etc.

This should be fixed in the latest update (484).
