[Rel-4_4 - Bug 10919] crypt password hash authentication type not usable

http://bugs.otrs.org/show_bug.cgi?id=10919

Hi Martin,

I tested this patch that reporter of bug attached. It worked for me. I suggested that somebody, who is more familiar with this, test this a little bit more. 
I was changing type of encrypting (e.g SHA-512, sha256, Blowfish, md5...) when is set CryptType to "Crypt" and it works fine in every cases. Also, I tested for all CryptType that is allowed in SysConfig now.
Note, that with this fix it is allowed to authenticate with SHA-512 encrypted password, but for me to test it, I had to change data table field in customer_user to  pw varchar(128) ( it was pw varchar(64) )
I think that we maybe should change something else to allow encryption SHA-512 completely.
At this moment I am not familiar with it enough, but if you want we can learn about it and do the changes in code.

Regards
Zoran
