Give good default for password generator based on base58

[gagarine]

The password generator let you chose your own schema.

Yet I think it would be nice to have some "default" you can click like the character set. In particular I may like to have a base58 option. Base58 is like Base64 but has been modified to avoid both non-alphanumeric characters and letters which might look ambiguous when printed. https://en.wikipedia.org/wiki/Base58

In my opinion, is the perfect character set because you can write it on any keyboard pretty easily. You don't lose that much entropy if your password is reasonably long enough (13 char).

It's a minor issue as I can set it by myself. Yet I think it would be cool so user can chose good schema without even knowing about it.
