wow. lots of rearranging

========================
* back to 1.2 structure
* moved h64 helpers into utils.h64 module
* pared down CryptHandler
* tightened UTs somewhat

+"""passlib.win32 - MS Windows support
+
+the LMHASH and NTHASH algorithms are used in various windows related contexts,
+but generally not in a manner compatible with how passlib is structured.
+
+in particular, they have no identifying marks, both being
+32 bytes of binary data. thus, they can't be easily identified
+in a context with other hashes, so a CryptHandler hasn't been defined for them.
+
+this module provided two functions to aid in any use-cases which exist.
+
+.. warning::
+
+    these functions should not be used for new code unless an existing
+    system requires them, they are both known broken,
+    and are beyond insecure on their own.
