also block access to the scripts directory.

working on making the install simpler, clone the directory and go

added comment to map_functions.inc

load_LinkerTO blows up in php7 due to the array not being created

The issue is somewhat dealt with, Eric is still working on it.

This commit is also a test of the git system.
cheers!
