Include local.make.example file in output

This serves three purposes:

• Allows people to build based on having both files instead of relying on packaging of d.o.
• Allows for people to include references to libraries / code bases currently not passing the white-list without an annoying README.txt telling them to download other stuff
• Lets us remove the checkbox for "local development" as this is the method of developing locally as a core is defined in this file while original make file is referenced as an include

An example proposed structure follows which gets twitter bootstrap and a distro and places them in the correct locations:

; CLE Local development file
core = "7.x"
api = "2"
; include the d.o. profile base
includes[] = "drupal-org.make"

projects[drupal][version] = "7.x"
