more default extensions to skip

Thank you for this feedback. I will look into adding these to the list of default extensions to be skipped. Of course you know that you can add then your that list yourself in each of the sites that you install my plugin. Please also keep in mind that with every extension skipped there is the possibility that files with those extensions may contain malicious code instead of the expected binary content, and this exclusion could undermine the effectiveness of the scan. Other fail-safe measures would need to be present to ensure maximum security, such as the scrutiny of include and eval statements to make sure that they are not used to execute code in these new file types.
