Possibility to hash password from console.

Currently setting a (non-plain text) password for a system user is quite cumbersome.

• Login to console
• Set hipposys:system to false
• Write changes to repository
• Login to CMS
• Change the password
• Login to console
• Set hipposys:system to true
• Remove hipposys:passwordlastmodified property (See: REPO-600)
• Write changes to repository

A button in the console to set a hashed password would be nice. A better fix would be to resolve CMS7-6875
