Modify pw to use 0 for default key length, which will then cause algorithum default hash size to be used, vs hard-coded default of '32'
Make salt_encoding option plugin specific by adding plugin prefix
Updated HashCompare to use new saltEncoding param, defaults to 'base64' and accepts 'utf-8' as alternative as-is (can easily be extended)
Add automatic key length setting to HashCompare, to accomodate non-standard hash lengths in comparison
Updated HashCompare compare calls across *all* plugins to use salt encoding param, either from supplied 'salt_encoding' option or defaulting to 'base64'
Updated pw util to include flags for salt encoding (default base64) and key length (default 64).
