Add config option to Tail to disable splitting on newline

[ghost]

I'm writing a script that'll tail a file and email me the changes to the file once a minute (if there are any). Right now, FileWatch::Tail splits new data by line. I'd like to add an open to FileWatch::Tail called :split_lines that gives you the option of splitting lines or not. It would default to true to keep existing behavior. It'd be something like this:

diff --git a/lib/filewatch/tail.rb b/lib/filewatch/tail.rb

I'd be happy to issue a pull request for that. I can also write tests for it to make sure that it doesn't break anything. If I do that, should I just use mintiest like you use on logstash?
