Layout changes, read extended description

*api moved to its own subdirectory and seperate admin directory created.

*htaccess policy set at root disabling directory listing and denying
access to certain file types (md files etc). Im considering denying all
except php files though, but this is good for now as I dont want it to
get in the way of dev

*OAuth somewhat installed, still testing though. I will have a database
update soon with extra OAuth tables added
