Update MimeTypes.py

When working with Non-MSIE Browsers, the validation/version detect for various Exploit Kits failed, as the mimeTypes were not found. e.g. Java Deployment Scripts (http://www.java.com/js/deployJava.txt, http://download.java.net/jdk8/docs/technotes/guides/jweb/otherFeatures/version.html).

This is a suggested fix. Possibly requires improvement and addition of more mimeTypes.
