Metaflac hex dump UTF-8 and locale fix.
Change metaflac hexdump function so utf-8 decoding is only used for
filename printing and changed hex output printing to not rely only
on isprint. That function seems to return true for tabulator
control character under Windows when application isn't using C-locale.
Patch (with one minor tweak) from Janne Hyvärinen <cse@sci.fi>.
