Archive files  such as zip or tar.gz are pretty common formats used by developers and more, and also by many programming languages that ship some artifacts as relabeled common archive types. We should add a content-type definition for them out-of-the-box.

From bug 106832:
'''
According to the ZIP specification, a ZIP file starts with: central a 4 byte signature: (0x02014b50). To support a ZIP content type, it would be just a matter of declaring it associated to the "zip" extension and using a BinarySignatureContentDescriber with the given signature.

A JAR content type could be declared (by JDT?) as a sub content type of the ZIP content type contributed by Runtime that just associates it to the "jar" extension. This would preclude JAR files that have the "zip" extension, but I think this might be good enough. Doing better than that would require further analysis of the ZIP contents, a price the content description mechanism can't afford to pay (not to mention manifests are optional, so JAR files are basically ZIP files that *we know* contain Java classes and resources in them).
