Add SecretToPublicKey function for ed25519 
Also remove IsClamped. Clamping occurs with ed25519, but it happens inside the Donna code. It is not needed elsewhere for ed25519.

Make SSE2 configurable via CRYPTOPP_SSE2_INTRIN_AVAILABLE 
Benchmarking shows things run a little slower with SSE2 on modern Core i5's. Also update comments and links

Fix the cut-in of Moon's implementation (GH #761) 
The initial cut-in was missing preamble present in Moon's curve25519_donna function. It originally tested good because we only perform a pairwise consistency check in release builds. Comprehensive testing with debug builds revealed the problem. Debug builds cross-validate against Bernstein's TweetNaCl library.

Cutover to Andrew Moon's 32-bit code (GH #761) 
The code is public domain without license restrictions. It is also faster than Langley's original implementation.

Add Moon's curve25519 using SSE2 (GH #761) 
Moon's code is very fast. In fact it is so fast it broke our benchmarks. Moon's code registers 0.00 milliseconds and 0.00 megacycles/operation.

Switch to library integer types 
The standard ints will cause trouble on older versions of Visual Studio. It looks like they were missed at the initial cut-in.

Fix failed self test when NO_OS_DEPENDENCE (GH #761) 
Add is_clamped for secret key validation.

Cleanup paramter names in Donna::curve25519 to follow function.

Overload Donna::curve25519 to implicitly use base point if not provided.

Add additional asserts to let the code debug itself.

Update documentation.
