Subject: [PATCH] Reduce log size in development/test environments

Code based on the logger Rails uses by default; as mentioned in the
Rails configuration guide:

> [the logger] defaults to an instance of ActiveSupport::TaggedLogging
> that wraps an instance of ActiveSupport::Logger which outputs a log to
> the log/ directory. You can supply a custom logger, to get full
> compatibility you must follow these guidelines:
>
> * To support a formatter, you must manually assign a formatter from
>   the config.log_formatter value to the logger.
> * To support tagged logs, the log instance must be wrapped with
>   ActiveSupport::TaggedLogging.
> * To support silencing, the logger must include
>   ActiveSupport::LoggerSilence module. The ActiveSupport::Logger class
>   already includes these modules.

Just like the documentation mentions, we're enabling log rotation using
"1" as the number of old files to keep and then the maximum size of the
log file.
