With the removal of Flash, there is no longer the need to return anything for navigator.plugins and navigator.mimeTypes. These APIs were used primarily for a) probing for Flash player support, or b) fingerprinting. Some sites use these APIs to probe for PDF viewer support. With this change, these arrays will return fixed lists containing a standard list of PDF viewer plugins.
Improve interop, remove fingerprinting vector, general API cleanup.
