*Now* bringing newsite up to speed

Syncing all the corrections helpful internet people made
Custom Axis docs/Improved viewport emulation

Backing up the docs. At this point it uses a visit tracker as an
example, but I'm going to get rid of it. Just want a record of it.
Edited custom axis docs

- Got rid of visiter tracking axis
- corrected some respond docs
- docs on intent.axes.axis.current
Added a blog post about new docs; cleaned up some wording

The new docs almost definitely needs a clean set of eyes to search for
typos
