Summarize your changes:
Basically as the title says, this implements a rename function to correct the file name of the .deb output to the user specified value. This also corrects the bin name to enforce the use of the executableName. In situations where the app name in the package.json does not match the executableName in the packagerConfig it errors due to package generating an executable following the executableName value which is not what MakerDeb is expecting.
