TODO:

o Write a GUI (GTK/QT/NCURSES)
o Add support for "gold accounts"?
o Maybe try to look for moved files when reading shares
o Reload config on SIGHUP
o Make captitalize_filename() turn abbreviations into uppercase chrs?
  eg. "BT - Flaming June.mp3", "GMS - Addiction.mp3" etc
  (if a word (len<4) has no vocals - make it all uppercase)
o Use int32 for filesizes internally
o Resume rollback? (eg. roll back 1024 bytes and compare)
o Minimum download speed (ie. drop downloads going slower than X KB/s)
o Save exit (ie. wait for current transfers to complete before exiting)
o GUI server
o NNVE xphsffN? (fganpveohy ba)
