Instrument Anything in Rails 3

With Rails 3.0 released a few weeks ago I've migrated a few apps and I'm constantly finding useful new improvements. One such improvement is the ability to log anything in the same way that Rails internally logs ActiveRecord and ActionView. By default Rails 3 logs look slightly spiffier than those produced by Rails 2.3: (notice the second line has been cleaned up)

	unless `git rev-parse HEAD` == `git rev-parse origin/master`
	puts "WARNING: HEAD is not the same as origin/master"
	puts "Run `git push` to sync changes."
	exit
	end

	extensions = ["js", "coffee", "css", "scss"]

	paths.each do \|path\|
