Non-'static' initializer

Reports non-static initializers in classes.

Some coding standards prohibit instance initializers and recommend using constructors or field initializers for initialization. Also, deleting the static keyword may accidentally create non-static initializers and result in obscure bugs.

This inspection doesn't report instance initializers in anonymous classes.

Use the Only warn when the class has one or more constructors option to ignore instance initializers in classes that don't have any constructors.
