Applied patch from Ticket 112.

Updated password method hash names to uppercase :
{crypt} to {CRYPT} and so on

TICKET DESC :
Currently some password classes use a lowercase password hashing scheme string in the userPassword attribute whilst others use an uppercase hashing string. rfc2307 and rfc2307bis do not dictate a standard but the uppercase string is a representation that is being used historically by different vendors, including OpenLDAP itself.

I propose to use uppercase everywhere (see attached patch). Since openldap/slapppaswd uses the uppercase notation itself I do not suspect any regressions on any deployed systems will occur.

I know of an application that syncs passwords from LDAP for internal usage and trips over lowercase representation (which is a bug in that program ;-) ). That bug showed me that GOsa didn't handle this consistently.
