Title: Introduce new iFrame attributes

This introduces entries for the following iFrame attributes:

* `sandbox`
* `seamless`
* `srcdoc`

Details on each attribute were previously requested for merge (see #186 #187 and #188), but upstream changes introduced conflicts. I've squashed commits containing requested edits to keep the project history tidy.
