Merge pull request #16 from asenchi/keys_everywhere

We should use keys everywhere
Fix tests.
Fix for Rails 3.2.9 changes.

See #18.
Add option to create logs in native Logstash format

We use the logstash-event gem for generating the output.
Document the log_format setting.
Test the logstash output
The logstash-event gem should only be required when necessary.

This means, users of the logstash output format have to install the gem on
their own. The upside is, that we still don't require the additional gem
for setups using only the lograge output.
