updated to compile on 10.8.3 / with brew hooks

unfiltered hightlight dir from gitignore.  added three scripts and
readme (see readme.txt in ./highlight dir.)
removed 10.7 framework hooks and added 10.8.  discovered that it was
looking in sdkver/Library/Frameworks when needed to look in
sdkver/System/Library/Frameworks for some of the referenced apple
frameworks.
