v2.3.0. Improvement.

- v2.3.0 January 19, 2013
	- Removed shrinkwrap file, hopefully dependency issues have been
resolved
	- Added `getSocket` configuration option so you can now use existing
sockets if you wish
	- Made the socket.io log level customisable via the `defaultLogLevel`
config option and now defaults to 1 unless in debug mode which defaults
to 3
		- Closes [pull request

	- Added the ability to customise the socket options via
`socketOptions` config option
	- Added the ability to customise the channel we listen on via the
`channel` config option, also changed the default channel from
`/docpad-live-reload` to `/docpad-livereload`
	- We will now log to the browser if we were reloaded by livereload,
this can be turned off via the `browserLog` config option
	- Added the ability to customise what happens at regeneration via the
'regenerateBlock' config option
