[NFR] Use recommended reason phrases for redirect

[oh-ren]

Currently, when using a redirect, no matter what status code is used, the reason phrase 'Redirect' is used.

This is not erroneous, but wouldn't it be more elegant / in accordance with the rest of the web to use the recommended phrases as listed in RFC 2616?:

301 Moved Permanently
302 Found
303 See Other
304 Not Modified
...

Relevant link: http://www.w3.org/Protocols/rfc2616/rfc2616-sec6.html

Cheers.

ps. is an issue like this considered to be a NFR?
The info over here: https://github.com/phalcon/cphalcon/blob/master/CONTRIBUTING.md does make me think so?
Could it be a good idea to make a distinction between suggestions (for improvement, like this one) and truly NEW feature requests?
