cleanup: Move modules to "lib/Crypto" subdirectory.

This will avoid the previous situation where scripts like the old "test.py"
get included accidentally in a release.  It also frees us to put additional
build scripts in the top-level directory of the source tree.

+"""Secret-key encryption algorithms.
+
+Secret-key encryption algorithms transform plaintext in some way that
+is dependent on a key, producing ciphertext. This transformation can
+easily be reversed, if (and, hopefully, only if) one knows the key.
+
+The encryption modules here all support the interface described in PEP
+272, "API for Block Encryption Algorithms".
+
+If you don't know which algorithm to choose, use AES because it's
+standard and has undergone a fair bit of examination.
+
+Crypto.Cipher.AES         Advanced Encryption Standard
+Crypto.Cipher.ARC2        Alleged RC2
+Crypto.Cipher.ARC4        Alleged RC4
+Crypto.Cipher.Blowfish
+Crypto.Cipher.CAST
+Crypto.Cipher.DES         The Data Encryption Standard.  Very commonly used
+                          in the past, but today its 56-bit keys are too small.
+Crypto.Cipher.DES3        Triple DES.
+Crypto.Cipher.IDEA
+Crypto.Cipher.RC5
+Crypto.Cipher.XOR         The simple XOR cipher.
