Use .webidl extension

This is a breaking change, motivated by a desire to work well with GitHub's syntax highlighting.

+The `addSource()` method can then be called multiple times to add directories containing `.webidl` IDL files and `.js` implementation class files.
 
 Finally, the `generate()` method will generate corresponding wrapper class files in the given directory.
 
-In this example, a file at `idl/SomeInterface.idl` would generate a new wrapper class at `wrappers/SomeInterface.js`, which would refer to an implementation class at `impls/SomeInterface-impl.js`. (In practice, usually at least two of these directories are the same, making `implSuffix` a useful option.)

 The transformer will also generate a file named `utils.js` inside the wrapper class directory, which contains utilities used by all the wrapper class files.
