Add ability to set a password when adding a user

[deeppunster]

Is your feature request related to a problem? Please describe.
Currently, when a new user is added, someone has to go into the admin menus to set the initial password.

Describe the solution you'd like
Add the ability to set the initial password for a new user when being added from System Maintenance ==> System User Maintenance ==> Add a New User Account.

Describe alternatives you've considered
A separate menu pick could be added for this, but that would be less convenient.

Additional context

• The constraints on the initial password should be the same as when a user changes their own password.
• No additional security constraints need to be added since only administrators and staff can get to this screen.
