Redundant field initialization

Reports fields explicitly initialized to their default values.

Example:

class Foo { int foo = 0; List bar = null; }
class Foo { int foo; List bar; }

Use the inspection settings to only report explicit null initialization, for example:

class Foo { int foo = 0; // no warning List bar = null; // redundant field initialization warning }
