build prod script.

[lramirez925]

Create a build script in box.json to build a deployable app.
It should produce the following 2 folders all zipped up in a deploy file.
zippedFolder/
liquibase/
src/

Got a quick and dirty version in #7.

Things left.
Create a way to export a zip file of the prod folder.
Should we auto clean all the files in the directory that are not committed?

Added the auto clean up in #8
