Deprecation warning when using with Rspec 3.2.2

[chrsgrrtt]

Fantastic Gem, solved a massive headache for me.

I'm encountering a slightly annoying deprecation warning when using with Rspec 3.2.2:

The Guard::RSpec::Formatter::NotificationRSpec formatter uses the deprecated formatter interface not supported directly by RSpec 3. To continue to use this formatter you must install the rspec-legacy_formatters gem, which provides support for legacy formatters or upgrade the formatter to a compatible version. Formatter added at: [...]/guard-jruby-rspec-0.2.2/lib/guard/jruby-rspec/runner.rb:49:in run

Perhaps the offending line could be removed? I can't tell if it's a hard requirement...
