#20 Patch: add backreferences in regex replace

[Heiner Eichmann]

Hi!

I have added the possibility to add backreferences in the regular expression replace string.
search: (.)((.))(.)
replace: :1[:2]:3
f.e. converts "band name (01) - title 1" into "band name [01] - title 1"

Best regards,

Heiner
PS.: This was my first programming attempt in perl. Please forgive bad programming style.
