Check application.ssl when setting a secure cookie

Most SLL-related code in Laravel checks to see if `application.ssl`
is true before doing an action requiring it. `Cookie::put()` is the
only exception that I've found, to date, that doesn't test for SSL.

This checks to see that the SSL is enabled when attempting to set a
secure cookie.

To verify, set `application.ssl` to false (without this patch) then
run:

	Cookie::put('foo', 'bar', 0, '/', null, true);

You will get an exception because of line 90 in `cookie.php`:

		if ($secure and ! Request::secure())
		{
			throw new \Exception("Attempting to set secure cookie over HTTP.");
		}

With this patch you will not get this error unless both `application.ssl`
is true, and the cookie `$secure` flag is set.
add macros to tables
get_dirty() comparison is not type safe

get_dirty() must compare using Not Identical (!==) on place of Not Equal (!=).
For example, changing null to false don't make the model dirty.

Changed Laravel\ namespace prefix in some classes calls in helpers to
global, to allow aliases to work, and allow class extending.
get_cli_option() is called outside Laravel app, so namespace prefix must be left there
