Validate strict mode

[nathggns]

At the moment, if you write a rule, and test it with data missing for that rule, it just ignores it. For example:

<?php
$validator = new Validate();
$validator->set('name', 'alphanumeric');
$validator->set('password', 'alphanumeric');
$validator->test(array('name' => 'Foo'));

That will pass. I think we should have an option where you can say if the Validator should error at missing values, and for missing rules.

So now we have this:

<?php
$validator = new Validate();
$validator->strict = true;
$validator->set('name', 'alphanumeric');

$validator->test(array('email' => 'scaffold.is.awesome@gmail.com'));
// Will Fail

$validator->test(array(
    'name' => 'scaffold',
    'email' => 'scaffold.is.awesome@gmail.com',
    'password' => 'scaffold'
));
// Will Fail

P.S. Yes, I know the branch name is incorrectly spelt.

Woops, did not mean for the patch1 commit to make it's way in. Please merge that pull request first.

No, just add a rule for checking if something is given/not empty.

We could have those as well as this, to be fair. I don't see any reason for not including this?
