Matt Nadareski 00a5c6c2c5 Convert HashType from enum to static class with constants 
Because the ordering of the enum was not guaranteed, both because of variances in .NET version and even library version, any change could mean that invisible version bumps would misalign. This attempts to fix that by converting HashType from an enum to a static class with a set of constants instead. This allows logical groupings and orderings without it affecting the values of each item.
