Multiple fixes

[cheald]

• Fixed secret_token being set by default. Instead, raise an error and instruct the user in how to generate their own token.
• Fixed multibyte string slicing bug in messages table view (for 1.9 only - is 1.8 supported?)
• Added test and development environments to the example configuration files to make it easier for developers.
• Minor: Updated Kaminari version to eliminate deprecated ActiveSupport::Concern usage, which was spamming up the logs with deprecation notices.

Thank you very much. Will merge tonight!

Most possibly not the test and development environments for the sample configs because they were removed on purpose as they were source of confusion for people setting it up.

Also notice that the tests are not supposed to run or succeed. They never were that good or complete and most of them were not changed for 0.10.0/0.11.0 releases.

This is one of the last Rails releases. I am already working on a complete rewrite using the Play Framework that is ready to grow and not end in such a mess that the current web interface is.

Yeah, I noticed that the tests weren't in working order. I did briefly entertain the thought of writing some new tests in rspec, but didn't want to complicate things too far!

Sorry for the delay. Will be included in soon to be release v0.12.0!

As already explained I reverted your changes to the environments in the example configuration files. Documentation updated regarding the secret token: http://support.torch.sh/help/kb/graylog2-web-interface/installing-graylog2-web-interface-on-debian-6

Thank you very much!
