Add sharedClass.disableMethod()

This adds a blacklist which can be added to using `sharedClass.disableMethod(name, isStatic)`.

The blacklist is checked when building `sharedClass.methods()`.
Please use a single empty line to visually delimit functions. Add a new line before each `beforeEach` and `it` line.
