Add additional Service Attributes to Standard Algorithm Names guide

The getProviders() code in the Security class does not allow for individual values to be searched, only exact string matches. Therefore, attribute lists such as:

    SupportedModes
    SupportedPaddings
    SupportedKeyClasses
    SupportedKeyFormats

are useless. Until this is fixed, I am choosing not to document these names in standard java names found in the the CryptoAlgs.html document (formerly Appendix A).

When this is fixed, these attributes should be added, along with their descriptions. We have attributes in Sun/SunJCE etc that should be added.

Let me know if this isn't clear.
