Address test_create_when_database_exists_outputs_info_to_stderr failures

test case for ActiveModel::Conversion#to_partial_path and namespaced models

Rename :value to :selected for date_select, and add missing tests/docs

When tested with ruby-2.0.0-rc1 `rake test` executes this test
even if the target adapter is not mysql nor mysql2.

Add tests for time & datetime.
Add documentation.

Adding tests for ActiveModel::Model

Allow to override the value on date_select

Now that we've fixed the fibs example, this is good to go.

* Verifying persisted? is false when Model initialized

the provided block.

In the case of having a form_for method being called, the block for each
collection would not be passed and thus the result expected was always the same.
This patch passes the block to the original method like it would be assumed.

Deprecate #update_attributes in favor of `#update`.

ORMs that implement `Generators::ActiveModel#update_attributes` should change
to `#update`. Scaffold controller generators should change calls like:

    @orm_instance.update_attributes(...)

to:

    @orm_instance.update(...)

This goes along with the addition of `ActiveRecord::Base#update`,
introduced in cb2bd4aa.

When running tasks such "rake db:setup", instead of showing messages
like "db_development already exists", it was showing a big stack trace
and a message "Couldn't create database for ..." with the configuration
options, a very confusing message with a big trace.

This brings back the functionality present in 3-2, showing the same
message.
