Dropping support for PHP 5.3 and PHP 5.3.3

[beryllium]

PHP 5.3 became an EOL unsupported branch in August of 2014. We should consider removing support for it from Sculpin, as well.

Continuing to support PHP 5.3 also means that I can't use my preferred choice of image manipulation library for PR #207.

doesn't react already force a php 5.4 requirement ?

@jrobeson No, it doesn't: https://github.com/reactphp/http/blob/v0.2.0/composer.json.

ah, not 0.2.0

The Sculpin Roadmap specifically states that Sculpin will continue to support 5.3.2 in Sculpin 2, and then Sculpin 3 will be based on PHP7.

I still support bumping Sculpin 2 to PHP 5.4, but I can see the reasons not to. If we don't bump it, I will likely rewrite PR #207 as an extension instead of a built-in feature.

@beryllium I'm not opposed to considering bumping Sculpin to 5.4 for Sculpin 2. The blog post was may be too specific on the 5.3.3+ support. :) I haven't looked at #207 close enough yet, but I'll get to making a comment on there now.

Bumping makes sense especially in the sculpin use case. We're not talking about legacy shared hosts that don't update their PHP. As far as I know that's the primary reason to support EOL'd versions. I think we're in a pretty safe space on this one as users do most of the PHP execution on their local machines and port static content to any non-php server.

Any updates?

FYI the Travis builds started failing on 5.3.3:

$ composer --prefer-source install
