Rewrite properties code

[wolfm]

• make the class include some sort of array/dictionary of defaults, set up beforehand
• Make it log everything it does and send errors loading properties to the driver station console.
• instead of calling a loadDefaultProperties method when one property fails: have the dictionary of defaults be within the class and set at the very beginning of robotInit(). Then, when one property fails to load when the getProperty() method is called, it will tell the DriverStation console and load back that .specific default.

instead of using an array or dictionary, I tried to use the Properties class itself. This may or ma not work, however, as most of the methods of the Properties class ask for Hashable Objects, not necessarily Strings, so I don't know what will happen until I test.

Possibly add a SingularityPropertiesError or PropertiesError for when a property isn't found in the file or in the defaults and the program ends up returning null
