version 0.08+ breaks under ruby 1.8.7

[ianheggie]

rake spec, script/server etc error out with versions 0.0.8 and 0.0.9:

rake aborted!
/home/ianh/.rbenv/versions/1.8.7-p374/lib/ruby/gems/1.8/gems/guard-rake-0.0.8/lib/guard/rake.rb:56: syntax error, unexpected tIDENTIFIER, expecting tAMPER
      ::Rake::Task[@task].invoke(*@options[:task_args], paths)
                                                             ^

Tasks: TOP => spec => db:test:prepare => db:abort_if_pending_migrations => environment
(See full trace by running task with --trace)

Workaround is to lock version in gemfile:

gem "guard-rake", '0.0.7'

Another workaround is to manually change ::Rake::Task[@task].invoke(*@options[:task_args], paths) to
::Rake::Task[@task].invoke(paths)

This should work for 0.0.9
