Just a little cleanup of a spec
Add humans txt settingso

Why a TXT?
ecause it's something simple and fast to create. Because it's not
intrusive with the code. More often than not, the owners of the site
don't like the authors signing it; they claim that doing so may make the
site less efficient. By adding a txt file, you can prove your authorship
(not your property) in an external, fast, easy and accessible way.

Really write to humans txt file
Add a text controller to manage humans.txt (and other later)
Robots.txt generated by a controller.

Perhaps we can add some cache instruction in this text_controller ?
