ignore attributes name and value by a predicate function

[dbarlev1]

I want to ignore some attributes that i only know part of them, for example start with "data-", currently it's possible to ignore only a specific attribute name.

Also to ignore values of attributes that contains some string or value longer then 100 char.

I think the best way is to give us the option to set ignore for attributes by a predicate function that we will pass in the options.

Thanks.
