This reverts commit 6626833d.

This commit breaks dumping a few tables, as the sessions table.
To reproduce, just create a new application and:

  rake db:sessions:create
  rake db:migrate
  rake db:test:prepare

And then look at the db/schema.rb file (ht: Sam Ruby).

This reverts commit 5b95730e.

Example:

  add_index(:accounts, :name, :name => 'by_name', :length => 10)
  => CREATE INDEX by_name ON accounts(name(10))

  add_index(:accounts, [:name, :surname], :name => 'by_name_surname', :length => {:name => 10, :surname => 15})
  => CREATE INDEX by_name_surname ON accounts(name(10), surname(15))

add_column and change_column in the Mysql adapter now accept some
additional options:
:first => true        # Put the column in front of all the columns
:after => column_name # Put the colmn after 'column_name'

add_column :new_col, :string, :first => true
add_column :another_col, :integer, :default => 0, :after => :new_col

Fix that creating a table whose primary key prefix type is :table_name generates an incorrectly pluralized primary key.

MySQL: treat integer with :limit => 11 as a display width, not byte size, for backward-compatibility.
