bakeProject should assume that source fileGlobs are relative to the new project directory

[abd3]

Right now, if we specify a source fileGlob that is a file at the top level of the project like "package.json" bakeProject does not replace template variables in that file. If we change it to include ** at the beginning (ex: "**/package.json") it works correctly. The replacements should assume that the fileGlob is pointing to the projectName folder. I see code in there to make that work, but I don't think it's working.
