added ability in ResourceContainer to save current mapping to a .properties file. not thoroughly tested.
added new mappings file that should please Duvall
you really dont really need to see newProp.properties. trust me
Merge branch 'master' of https://github.com/aaronkrolik/CS308FinalProject_Inputs

I added a new resource file Game1MappingsNew_en_US.properties that follows the "behavior" -> "manyKeys" paradigm duvall suggested. also ResourceContainer can now write files. be warned.
