www/subsonic-standalone license

[Michael Zhilin]

Hi,

Issue: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=213299 (created 20
days ago).

License of www/subsonic-standalone is GPL [1], but actually this version of
software (v.6) is available only as free binaries. Also it includes trial
version of functionalities which can be purchased by subscription.

Could you please look at this issue?

Thank you in advance!
