Fixes article editing + build

I definitely agree that the way I fixed routing specs may seems
strange, I think it's because it was designed to be used on a
resourceful model, which we don't anymore.
Rebrands Typo as Publify

Typo as a brand has just been a nightmare to use.

Even though it's a 7 years old project, no one in the community
remembers it except maybe as the bloatware it became at some point.

Many reasons made us change:
1. Typo is a nightmare to search.
2. There's a publishing too called Typo3 that has been around for more
than a decade.
3. It's too much related to typography
4. Typo as a tool to produce quality content is a nice pun, but a pun
anyway.

So long live publify!
