+ Add "contains" and "not_contains" operators and elements to
font configuration
+ Changed semantics of eq operator for LangSets to check for
FcLangEqual so that any match will do
+ FcFontList was using FcConfigCompareValue (...FcOpEqual) instead
of FcValueEqual to check for identical values when inserting into
the results. This broke when the above semantic change was made,
now it uses FcValueEqual which is "more correct" in any case.

+ Reimplement FC_LANG as new datatype. Lists of strings
