Enhancements for Password::randomPass()

[Toutouwai]

Short description of the enhancement

This is a request for a couple of enhancements to Password::randomPass().

1. An option for maxLength to apply to the whole generated password. Currently there is no way to control the total length of the generated password when digits and symbols are included. I can't think of a scenario where you wouldn't want the maxLength to apply the whole password, but if there is some need for this then a new option could added for max total password length.

2. An option to generate a password based on the settings of a given FieldtypePassword. It would be useful if as many settings as possible could be pulled from the password field/inputfield (not sure how easy it would be to support the "complexify" setting) so a password could easily be generated to satisfy the settings of a given field.

Also, in the randomPass() method, why is there no maxLower option and also minLetters and maxLetters options. These last two would seem to be essential if you're trying to build a password that adheres to the settings of a given FieldtypePassword field because it has the option for "letter" which doesn't specify case.
