This function should be useful when you need to log during async
parallel operations, without having a mess in logs.
For example when you walk asynchronously a directory and you want logs
to be grouped by file.
It returns the same getLogger() object but messages are stored
internally and sent to appenders only when you call the flush() method
on it.
According to the GELF spec v1.1 [1], the full_message field in GELF is
optional. The log4js implemention until now has sent identitical
short_message and full_message fields. Since this does not add any new
information to the log message, I suggest that full_message be dropped
from GELF.

It turns out that whenever the clusterred appender is used the log event is passed to all actual appenders.
The actual appender's category is ignored.

Updated logger.js to support disabling all log writes.
Updated log4js.js shutdown function to disable log writes.
Added tests.
Update gitignore to ignore rolling date stream's test output.
loadAppender will check for a shutdown function exposed by
a loaded appender. If present, it will be cached so that the
shutdown function can execute it.
The intent here is that a Node application would not invoked
process.exit until after the log4js shutdown callback returns.
Previously, appenders could only be added by specifying the filepath
to the appender. This required the appender's path to be specified
either relative to the log4js installation, relative to a NODE_PATH
token, or absolute. This creates a coupling between the log4js
configurer and the log4js installation location, or a coupling between
the log4js configurer and the global NODE_PATH. This commit removes
the coupling by allowing the loading of appenders to be done relative
to the log4js configurer.
using levels.toLevel and this.isLevelEnabled prior to emiting the event will prevent the appenders from being notified if the log level provided is below the loggers level.
Stop making use of any layout by default, because they are intended to
format a line for human reading. Loggly indexes the values (of all
properties of objects) and makes them available for querying.
