	  These objects are now more self-loading and just need to be
		passed a dict of their config options.
	* Changed to using packages for monitors, loggers and alerters.
	* Fixed bug where initial failure time was always the most recent
	  failure time.
	* Fixed a bug with the DiskSpace monitor which meant the free space
	  on non-Windows platforms was incorrectly calculated.
	* Changed the intention of the DiskSpace monitior on non-Windows
	  platforms to measure the non-superuser free space.
	* Fixed a bug which could mean the main loop ignored the interval
	  if an error occurred during tests.
	* Better support for the dry_run setting on alerters
	* BulkSMS sender now limits messages to 160 chars (otherwise BulkSMS
	  rejects them).
	* Formatted times in alerts to not include microseconds

	+ Monitors now know their own name
	+ Alerters now have configurable time ranges for operation.
	+ Alerters now have days of operation.
	+ Alerters can hold alerts that occur out-of-hours and update you
	  if the monitor is still failed when they become in-hours.
	+ Email alerts for failure now include downtime (which will be 0 for
	  an alert that fires immediately, but may be useful for alerters with
		a limit).

<= 1.1:
	* Changes not tracked.
