CacheDigests: Support templates in directories several levels deep

assert_template works when the same partial was rendered multiple times

No need to test for rack-cache present in gem file

this refactoring extracts the semi complex data structure of rendered locals
per view into into a separate class

Expand the caveat about models in migrations in the rails guide.

Eager autoload Preloader classes

Without eager autoloading, these would be autoloaded
only when #preloader_for is called, which is too late
in threaded applications.

This is an attempt to address issue #6939, where an earlier migration
added a column to the database, and a later migration uses a model and
references that column.

When both migrations were run together with `rake db:migrate` the column
information in memory still referenced the old table structure.

Running the migrations separately fixed this, as a new connection was
then established before referencing the model. Explicitly calling
`reset_column_information` is a more reliable workaround.

remove duplicated require statements in AR test cases

Build failed with an error "invalid multibyte char (US-ASCII)" in these
files. Apparently, some UTF-8 char disguised as whitespace causes this.
