Add UI to let manager change users password

A submenu has been added to the side menu's
'Edit user account' option. This submenu has
two options:

- Reset password via email: an email is send
so that the user can change their password by
themselves.
- Reset password manually: the manager has to
write the password manually (or generate a random
one).

The passwords generated by the random password
generator don't contain characters like $ or !.
It uses some capital letters, some other lower
case letters and some numbers. Ambiguous
characters like 1, l, I has been removed.
