Fixed bug creating invalid HTML in select options

When a select tag is created for a field with errors, and that select
tag has :prompt or :include_blank options, then the inserted first
option will errantly have a <div class="field_with_errors"> wrapping
it.

Only use prepared statements when bind variables are present

Prepared statements (prepare/execute/close) were being used unnecessarily
when no bind variables were present, and disabling prepared statement using
prepared_statements:false was principally broken. While bind variables were
correctly substituted with prepared_statements:false, the prepared statement
interface was still used, costing an extra two round trips per query.

In addition to making this behavioral change, I also cleaned up the internals
of exec_stmt and exec_without_stmt so that they behave the same (calling log
and constructing the ActiveRecord::Result in the same way).

Moving the check for binds.empty? to exec_query also will mean that several
code paths explicitly calling exec_without_stmt could be cleaned up to once
again call exec_query instead. I have also left the check for binds.empty? in
exec_stmt, since it is not a private method and could be called directly with
an empty binds array. For the sake of clarity in this patch, I have not made
those changes.

= The previous behavior =

When issuing a Foo.find(1) with prepared_statements:true, the bind variable
is present in the prepared query, and execute shows a value passed:

    Connect	root@localhost on rails_test
    Query	SET SQL_AUTO_IS_NULL=0
    Statistics
    Query	SHOW FULL FIELDS FROM `foos`
    Query	SHOW TABLES LIKE 'foos'
    Query	SHOW CREATE TABLE `foos`
    Prepare	SELECT  `foos`.* FROM `foos`  WHERE `foos`.`id` = ? LIMIT 1
    Execute	SELECT  `foos`.* FROM `foos`  WHERE `foos`.`id` = 1 LIMIT 1
    Close stmt
    Quit

When issuing a Foo.find(1) with prepared_statements:false, the bind variable
has already been removed and substituted with the value, but the prepared
statement interface is used anyway:

    Connect	root@localhost on rails_test
    Query	SET SQL_AUTO_IS_NULL=0
    Statistics
    Query	SHOW FULL FIELDS FROM `foos`
    Query	SHOW TABLES LIKE 'foos'
    Query	SHOW CREATE TABLE `foos`
    Prepare	SELECT  `foos`.* FROM `foos`  WHERE `foos`.`id` = 1 LIMIT 1
    Execute	SELECT  `foos`.* FROM `foos`  WHERE `foos`.`id` = 1 LIMIT 1
    Close stmt
    Quit

= With this patch applied =

When issuing a Foo.find(1) with prepared_statements:true, the bind variable
is present in the prepared query, and execute shows a value passed:

    Connect	root@localhost on rails_test
    Query	SET SQL_AUTO_IS_NULL=0
    Statistics
    Query	SHOW FULL FIELDS FROM `foos`
    Query	SHOW TABLES LIKE 'foos'

    Execute	SELECT  `foos`.* FROM `foos`  WHERE `foos`.`id` = 1 LIMIT 1
    Close stmt
    Quit

When issuing a Foo.find(1) with prepared_statements:false, the bind variable
has been removed and substituted with the value, and the query interface is
used instead of the prepared statement interface:

    Connect	root@localhost on rails_test

    Statistics
    Query	SHOW FULL FIELDS FROM `foos`
    Query	SHOW TABLES LIKE 'foos'

Add support for optional root segments containing slashes

Optional segments with a root scope need to have the leading slash
outside of the parentheses, otherwise the generated url will be empty.
However if the route has non-optional elements then the leading slash
needs to remain inside the parentheses otherwise the generated url
will have two leading slashes, e.g:

Blog::Application.routes.draw do
  get '/(:category)', :to => 'posts#index', :as => :root
  get '/(:category)/author/:name', :to => 'posts#author', :as => :author
end

$ rake routes
  root GET /(:category)(.:format)              posts#index
author GET (/:category)/author/:name(.:format) posts#author

This change adds support for optional segments that contain a slash,
allowing support for urls like /page/2 for the root path, e.g:

Blog::Application.routes.draw do
  get '/(page/:page)', :to => 'posts#index', :as => :root
end

$ rake routes
root GET /(page/:page)(.:format) posts#index
