[Bug]: Unable to set login passwords longer than 31 characters

[danidoedel]

Version of OpenTTD

13.3

Expected result

It should be possible to set community (citymania, n-ice, btpro) login passwords longer than 31 characters.

Actual result

Tested this with the citymania login. If a password longer than 31 characters is set via gui it will be truncated to 31 characters and the login will fail. Login via the !login command works fine for longer passwords.

Steps to reproduce

1. Set a password longer than 31 characters via the gui
2. Click login
3. Login will fail and a truncated password will be displayed in the chat
4. Alternatively open the password gui again which will also show the truncated password

Increased to 127. Didn't test much though.
