fix uninitialized constant Logger::SimpleFormatter

[btatnall]

Namespace SimpleFormatter properly so the following error doesn't occur.

Footnotes Log Exception: uninitialized constant Logger::SimpleFormatter

Error was created using the following environment:
rails 4.1.4
jruby 1.7.10
Rails.logger set to an instance of Log4r Logger.

Thanks!

I'm on vacation right now, I'll release the a minor version when I reach a computer.

I just released version 4.1.1 with your fix, thanks

Indeed. It will break if a custom logger that does not inherit from the standard Ruby Logger is set.

@btatnall What was the original issue with Logger::SimpleFormatter ? Is it not defined in Jruby ? Or was there an issue with the namespacing only ?

If it's the latter, we could fix it by using ::Logger::SimpleFormatter

Ok so after a quick check SimpleFormatter is activesupport, my bad.

It's not defined in 3.2, so this code already broke before this PR.

TODO:

• Find another way to perform the log note without Logger::SimpleFormatter
• Add specs on this code where there is no Rails Logger

[btatnall]

Using log4r the constant was not defined.

@bteitelb this should be fixed thanks to #125, I'll add some specs and release ASAP
