custom build tool - FLUID 3008

[Laurel A. Williams]

Hi all,

More php code for review in the incubator/custom-build project.

This is the last commit to address the issues that Colin mentioned in 
his email reviewing the postProcessor code. I have written a function to 
dynamically obtain an array of modules from the build.properties file - 
you can find the new function in BuilderUtilities (retrieveModuleList). 
I also wrote tests for the part of this function that parses the data 
from the build.properties file. In addition I altered the code in 
postProcessor and PostClass to use the new function.
