Multiline announce parser does not work for BTN

[pisserman420]

Hey, I've had no problems using this program on AHD and PTP, but on BTN it throws an error when trying to parse the announces. BTN works fine in autodl-irssi. There's some examples of BTN's announce format over here.

Yes, that is certainly a case I have totally missed. I will look into it. Thanks for the feedback.

[weannounce]

I pushed a fix for the most immediate concern to master https://github.com/weannounce/arrnounced/commit/bfc13c270bbec870b01a6a79950e3115e997c9a6

I also see the BTN configuration is doing some other stuff which is not support at the moment, like creating the release name using other fields. I will look into that as well.

As of commit 7458c6c73eb4b51d13d53abdb93cfe8f0fddbc72 BTN should have full support.
