Feature Request: Add "Uppercase" option to random password generators

Hi Dave,

The memorable password option comes closer, but it still doesn't provide the same capability as the random password generator would provide if it had the ability to disable uppercase letters (this feature request).

I want to generate a lowercase-only password (i.e. no dashes or other characters) where every character is completely random (i.e. the letters don't spell memorable words) so that it's as short as possible for a desired number of bits of entropy while still being easy to type using a TV remote or other limited input device.

Implementing this feature request is the only way to get that, and other password generators already have this feature. See https://www.lastpass.com/features/password-generator as an example. I recently switched from LastPass to 1Password due to it's reputation for security, but I was surprised to find a simple feature like this was missing from 1Password.

Thanks in advance!
