remove verbiage about --sector-align only working for WAVE files since it works for all kinds of input now

add support for raw and aiff input in the multifile tests; also add proper checking for the correct operation of --sector-align

fix bug in --sector-align where appended samples did not completely contain silence (SF bug #1237707: https://sourceforge.net/tracker/index.php?func=detail&aid=1237707&group_id=13478&atid=113478).  also, fix bugs with --sector-align on raw files

add support for encoding from non-compressed AIFF-C (SF bug #1090933: https://sourceforge.net/tracker/?func=detail&atid=113478&aid=1090933&group_id=13478)

disallow non-shortest-form encodings in utf-8 checking; when converting utf-8 to ucs-2, replace code points outside of ucs-2 with ? character

check that a cuesheet is legal before trying to encode with it so user will get a more useful error message; only warn about non-CDDA-compliant cuesheets instead of error

fix bug in cuesheet parsing where it would return an error if the last line of the cuesheet did not end with a newline

change the navbar css by integrating the separators into it.  IE was treating the empty separator div's differently than everything else and putting space in them
