Add RFC 2307 hash detection support to --hash

RFC 2307 (Experimental) suggests user passwords be hashed using a one-way (hopefully) cryptographically safe algorithm. They are often referred to as being "encrypted", but this is a misnomer (as they are not designed to be decrypted).

OpenLDAP supports RFC 2307 hashed passwords, including the {CRYPT}, {SSHA}, {SHA}, {SMD5}, {MD5}, and other schemes. Such passwords may be used as userPassword values and/or rootpw value.

Note: use of RFC 2307 Experimental passwords violates the Standard Track specification, RFC 2256, for user passwords and may lead to interoperability problems.

For this hash type you mean something like:
{md5}5f4dcc3b5aa765d61d8327deb882cf99?

If not, could you give some examples?
