#1232 Make ShortClassName configurable

[blundell]

Isbn.java:3, ShortClassName, Priority: Normal
A Classname should have a minimum of five characters.

Card.java:7, ShortClassName, Priority: Normal
A Classname should have a minimum of five characters.

Isbn & Card are both valid class names, should this rule be changed to four characters?

[Anthony Whitford]

You could annotate these two classes like @SuppressWarning("PMD.ShortClassName")

But I also like the idea of having a variable for the minimum, like for LongVariable.

I've implemented this as a feature-request. With the next release, you can configure the rule via the property "minimum". By default, this will be still 5 characters, but you can change it to four then.
