Drop incompatible PHP versions

[szepeviktor]

symfony/filesystem 3.0.x-dev requires php >=5.5.9

@diggy Have you seen this one?

[diggy]

@szepeviktor Yes, in fact I'd like to improve support rather than drop it, cf. Chouby's effort with Polylang proper to reflect WP's min req. Could you explain exactly why WP-CLI core is able to run on 5.3 and this package would require 5.5.9 or higher (apart from the fact that it's currently using traits, incompatible syntax etc)?

Now I see that wp-cli has an alternative dependency version
https://github.com/wp-cli/wp-cli/blob/master/composer.json#L33

Why Travis is trying with the higher, incompatible one on PHP 5.3/5.4???

I've started an UpCould instance with Debian 7 with PHP 5.4:

Maybe composer is badly caching on Travis?

[szepeviktor]

Or old composer version is forced?
https://travis-ci.org/diggy/polylang-cli/jobs/241538140#L155

But

Composer requires PHP 5.3.2+ to run.

@szepeviktor my composer-fu is rather limited, what about this:

• we're requiring "wp-cli/wp-cli": "~1.2.1" (cf. https://github.com/diggy/polylang-cli/blob/master/composer.json#L20)
• "prefer-stable": true is currently missing in composer.json
