The filter panel previously did not pack filter labels homogeneously, so

the width of the "Unofficial" label was being manually constrained by
abbreviating it. Labels auto ellipsize and adjust now, so the full name
is used. The filter file check is also allowed to fail if the user's
filter preferences file contains old key names.
