FieldRenamer does not respect exclusion

[micartey]

FieldRenamer does not respect exclusion on neither root level nor same level defined list.

1.Exclude all fields in class. "net/spartanb312/Example1"
2.Exclude specified field in class. "net/spartanb312/Example2.myField" (notice: all the fields witch name starts with myField will be excluded)
3.Excluded all classes. "net/spartanb312/"

In next version, I will optimize the exclusion system

Hi, any updates on this? I'd like to suggest some kind of regex-based exclusion system for packages, classes, methods, and fields. This is also slightly related to #54.
