Before this patch, every request in development caused the template
to be compiled, regardless if it was updated in the filesystem or not.
This patch now checks the timestamp and only compiles it again if
any change was done.

While this probably won't show any difference for current setups,
but it will be useful for asset template handlers (like SASS), as
compiling their templates is slower than ERb, Haml, etc.

This means that templates does not need to store its source anymore, allowing us to reduce the ammount of memory taken by our Rails processes. Naively speaking, if your app/views contains 2MB of files, each of your processes (after being hit by a bunch of requests) will take 2MB less of memory after this commit.

This is extremely important for the upcoming features. Since Rails will also render CSS and JS files, their source won't be stored as well allowing us to decrease the ammount of memory taken.

The phrase "clean up" misrepresents the fact that this removes
a feature that ships with Rails 3.0.

This reverts commit 6774e12a.
