Conditional element method calls

[jesseleite]

Similar to the existing magic attribute setters:

Form::text('meme')->lol('catz')
// <input type="text" name="meme" lol="catz">

This PR proposes conditional magic attribute setters:

Form::text('name')->disabledIf(true)
// <input type="text" name="meme" disabled="disabled">

Form::text('name')->disabledIf(false)
// <input type="text" name="meme">

Form::text('name')->maxlengthIf(true, '5')
// <input type="text" name="meme" maxlength="5">

Form::text('name')->maxlengthIf(false, '5')
// <input type="text" name="meme">

This works using the magic __call() method, detecting if last two characters in method call are If. The first param being $condition (can be any expression), and the following params are just passed onto the desired method using call_user_func_array().

This is very nice!

What about this :

{!! BootForm::open()->action(route('companies'))->multipart()->putIf($company->getKey()) !!}

So we don't have to do this:

@if($company->getKey())
    {!! BootForm::open()->action(route('companies'))->multipart()->put() !!}
@else
    {!! BootForm::open()->action(route('companies'))->multipart() !!}
@endif

Edit : And ofcourse i mean Form::open() ..... :)

@axyr Because my code is on Element, and because FormOpen extends Element, this is already possible:

Great!

@adamwathan can you merge some of the very very nice pull requests???

I know this was implemented in #99, but my case for magic method implementation here: #99 (comment)

...That said, if you want to close this PR, I won't be sad :)
