Add `allPropertiesRequired` and `noAdditionalProperties` options

[a-lavis]

Adds the allPropertiesRequired and noAdditionalProperties options. Each of these options include a subset of the functionality that strict provides.

Here is how the three options interact, as a truth table:

strict	allPropertiesRequired	noAdditionalProperties	All Properties are Required	Additional Properties are not Permitted
T	*	*	T	T
F	T	T	T	T
F	T	F	T	F
F	F	T	F	T
F	F	F	F	F

These changes are not breaking - strict behaves the same way that it did previously.

Rubocop is complaining that test/draft4_test.rb is too long - not sure what the best way to split up the class is. Any ideas?
