Added the documentation.pdf file and modified build.xml so it will copy it into dist/public/
Modified web files for a different styling and to make the "select" responsive to up & down arrow keys release
Added in Rest handling options for DELETE Role and PUT Person, also tested them
Added removeRole and editPersonFromGson to PersonFacade, I tested them with PostMan and work perfect
I deleted the list of Persons from PersonFacade because it was useless there; this interferes with one of the tests :/
