This adds some additional checks for the inputs of some Prism functions.
They work by replacing a function to test with another function calling both the test code and the original function.
This allows us to add complex checks without adding weight to Prism core.
Right now, I added checks for
Prism.languages.extend
andPrism.languages.insertBefore
.This resolves #1717.
