Update _768up.less

I was working with bones and found a small error under navigation, 'li.current-page-ancestor' should be 'li.current_page_ancestor' (2 occurrences).

I am new to programming, learning to make wordpress themes. :)
Fix accessibility issue in the menu and cleaned up some CSS.
fix classname li.current_page_ancestor

It was li.current-page-ancestor before. wordpress uses li.current_page_ancestor

reworking the Sass directory

let’s break things out into a setup that’s condusive to larger projects.
removing unused or older Sass files

we’re updating this whole structure, so let’s remove the old ones and
clean it up
Removing LESS

Sorry LESS users, we’re going Sass only now. If anyone wants to create
a repo with LESS, I’m all for it.
moving this directly into the functions.php file, no need to have it on it's own.
making it a .txt and not a uppercase thing.
adding post format templates

this makes things a bit complicated but it’s easy to disable so let’s
give people the option.
cleaning up the functions file

removing alot of stuff to make it even easier and simpler to read.
adding the launch bones into functions to make it easier to use.
removing search function
adding a google font thing, just to make things pretty (easy to remove)
adding menu call right in the header

creating another function seemed like overkill. Let’s just drop it
right in there.
adding  new css and some new notes
adding new grid styles

these aren’t working yet, but they will be very shortly.
removed a ton of stuff to make it use more WordPress defaults
putting footer menu right in the footer
logging stuff

very little changes here
removing a ton of stuff

again, very simplistic. i removed functions i thought were overkill or
are now included in WordPress core
updating the log
